I'm at the last step of the process and can't get over this hump! We've successfully logged in, selected the team to have the .zip file associated with, but this path error comes up.

Any assistance as to why the given path's format is not supported would be great! I am not an administrator or programmer so please do be gentle!

Unhandled Exception: System.NotSupportedException: The given path's format is not supported.

AFAIK, ms teams now does support private teams. Can this tool support that?

Good day,

This is hardly the best way to do this but I needed to get it to work quickly, it turns this message:

<@SD578SDSS> joined the channel

into this:

@Steven_User Joined the channel

Call From code:

static List<Models.Combined.AttachmentsMapping> GetAndUploadMessages(Models.Combined.ChannelsMapping channelsMapping, string basePath,
List<ViewModels.SimpleUser> slackUserList, String aadAccessToken, String selectedTeamId,

bool copyFileAttachments)
{
.
.
.
var messageTs = (string)obj.SelectToken("ts");
var messageText = (string)obj.SelectToken("text");

if (messageText.IndexOf("<@") > -1)
{
messageText = ReplaceQuotedUsersInMessage(messageText, slackUserList);
}
.
.
.
}

Procedure:

static string ReplaceQuotedUsersInMessage(string MessageText, List<ViewModels.SimpleUser> slackUserList)
{

for (int i = 0; i < slackUserList.Count; i++)
{
if (MessageText.IndexOf("<@") > -1)
{
MessageText = MessageText.Replace(string.Concat("<@", slackUserList[i].userId, ">"), string.Concat("@", slackUserList[i].real_name.Replace(" ","_")));
}
else
{
break;
}
}

return MessageText;

}

I'm able to login and successfully create channels, but I seem to be missing a permissions setting as I'm getting an error - Folder creation failure: Microsoft.Graph.ServiceException: Code: accessDenied

Here is a way to convert timestamps into pretty datetimes:

if (messageTs != null)
{
System.DateTime dateTime = new System.DateTime(1970, 1, 1, 0, 0, 0, 0);
dateTime = dateTime.AddSeconds(Convert.ToDouble(messageTs));
dateTime = dateTime.ToLocalTime();
messageTs = Convert.ToString(dateTime);

                        }

Hi,

I am encountering an error when running dotnet with ChannelSurf. I am a non-administrator user of microsoft azure. After following instructions I encountering an error that tenant is not found. Please see screenshot below.Thanks.

We have installed .NET 1.1 (as well as the dependencies for 1.1.2) but when we select the Destination Team we get the following error:

Any idea why this is happening? We have tried to build from fresh as well as perform the channel.json, but the same error happens.

Let's get started! Sign in to Microsoft with your Teams credentials:
To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code ***** to authenticate.
You've successfully signed in. Welcome ********

C:\Users\jdoe\source\repos\ChannelSurf\ChannelSurfCli>

This is where I am stuck in the command prompt.
The instructions says "Select the target Microsoft Team you want to create or re-create your channels into. You can also choose to create a new Microsoft Team."

Where do I select the target team??? Am I missing something obvious?

I also tried to write a (HipChat to) Teams migration utility (https://github.com/Lombiq/HipChat-to-Microsoft-Teams-Migration-Utility) but I couldn't get attachments working. Apparently this is not possible via the API, despite it appearing as being working: https://techcommunity.microsoft.com/t5/Microsoft-Teams/Graph-API-Issues-while-creating-new-chat-thread/m-p/242558

Do posting file attachments to Teams messages still work for you?

Thank you!

While running the script to migrate existing channels, I'm getting this error. This is a duplicate of #24 which has been closed prematurely without a solution in place

Good day,

First off thank you very much for this it helped my tremendously.

I found a small mistake in your code in the procedure: static void CreateSlackMessageHtmlArchiveFile the write to HTML was taking the first 250 lines every time instead of being incremented with messageIndexPosition.

Also the HTML file being produced did not have any CR LF in the file causing it to become unmanageable "wide".

StringBuilder fileBody =new StringBuilder();
fileBody.Append("");
for (int i = messageIndexPosition; i < messageIndexPosition + numOfMessagesToTake; i++)
{
var messageAsHtml = MessageToHtml(messageList[i], channelsMapping);
fileBody.AppendLine(messageAsHtml);
}
fileBody.AppendLine("");
messageIndexPosition += numOfMessagesToTake;
w.WriteLine(fileBody);

I've carefully followed the instructions on https://github.com/tamhinsf/ChannelSurf, at least as far as combining the JSON exports from "dailies" to full channels (successful) and attempting to convert those to HTML (not successful). I've run into a problem with the links to pasted images and attached files.

Neither of those things are transferred to the HTML. Avatar pictures are included, but images pasted into messages and attached files are simply dropped. If anyone is interested, I can copy the relevant code snippets here. Any suggestions?

I have installed required .net framework and trying to configure the teams through CMD a explained under "Using" section - however
I am running through below error - can you please help?

Hi,

Context

I successfully build the the project but i can't run it in debug mode. It is probably related to my Visual studio installation.

I've VS 2017 Community 15.8.2 and i've installed .NET Core SDK,

Error

The error i get is :

Le programme '[13724] dotnet.exe' s'est arrêté avec le code -2147450730 (0x80008096).

The program ... stopped with the code ...

Suggested workaround

I am surprised that I can't find the exe itself after I build, can somebody share the .exe file ?

Thank you,

You'll need to rewrite history to get rid of this..

can you use this tool to migrate conversations between Teams channels?

Readme.md says 'Copy Slack file attachments into Teams', but this hasn't worked.

It's brought all the channels and messages over in html files beautifully, but no images.

Any ideas what I might have missed?

Thanks.

One or more errors occurred. (AADSTS7000218: The request body must contain the following parameter: 'client_assertion' or 'client_secret'.

Please advise.

I am stuck on issue that is already reported here and seen no response activity since 2020 https://github.com/tamhinsf/ChannelSurf/issues/25 .

My question is is this worth troubleshooting further, or is this dead end?

Welcome to Channel Surf!
This tool makes it easy to bulk create channels in an existing Microsoft Team.
All we need a Slack Team export ZIP file whose channels you wish to re-create.
Or, you can define new channels in a file called channels.json.

The migration process seems to be running mostly smoothly. I only get a few messages about already existing items like:

Folder creation failure: Microsoft.Graph.ServiceException: Code: nameAlreadyExists
Message: The specified item name already exists.
Channel folder exists
This channel already exists in MS Teams: General

Which may be related to the fact that both MS Teams and Slack have the default "General" channel and that I've already done several migration tries now.

I also get a couple of these, which might be related to the same "already existing items" cases, I'm not sure:

Inner error

Anyway, it does its thing including Trying to upload file to MS Teams SPo Folder, Upload of attachment to MS Teams completed, Migrating messages in channel, asks me whether to create some HTMLs and ends with

Scanning messages in Slack channels - done
Tasks complete.  Press any key to exit

I see that the channels are created.
In the files tab, I see a folder channelsurf which contains folder messages, which in turn contains folders html and json, which then contains 0.html and 0.json respectively. (And some bigger channels may contain also 1.html and 1.json etc.)
Those .html files contain the chat messages.

But the channels themselves do not contain any imported messages. I tried also to log out and back in again. And tried to open Teams in both the web browser and the Teams app, still nothing.

Any ideas?

Could this be related to the users not matcing? As I'm trying this in a test team, where no other users have been added. But it should at least show my own messages, right? How are the users matched?

I'm running into this when loading the project into Visual Studio:

Any advice appreciated

All channels are migrated except the private channels.
Private channels exist in the slack export file but are not being migrated.
I'm not sure what the issue is. Any help?

I imported one rather small channel and I'm looking at the HTML file of messages compilation ChannelSurf created for me. The message order is a mess...

The first message is from the 18th of February which is more than half in the whole discussion history. The messages are displayed successively until 4th of March (which is not the last day of messages), then jumps back to 21st of January. Then, after a few messages, jumps to the 27th of February (and, no, it's not the same thread). Then again, back to the 7th of February, and then back to the 15th of January which, at last, is the actual first messages of the channel history.

And after that, the jumping goes on and on. And it's not explainable by threads. Although, another issue – which would be a new feature request, I guess – is that the threads are not distinguishable visually, in the imported compiled HTML. All the messages are listed in one, plain list.

The content export ZIP from Slack contains the JSON files named by the dates, and they seem sorted correctly. So, there is nothing there for me to fix, it's ChannelSurf that mixes all the dates.

I thought it would be nice to import the Slack messages into MS teams as messages, so I developed a bit of (ugly!) code to do so. I stuck this method in messages.cs, and jammed the call to it into CreateSlackMessageHtmlArchiveFile. The best part about these posts as opposed to those from a webhook is that they're searchable. It will churn along happily, posting messages to the appropriate team channel, until it hits the Activity Limit for the API returning

REASON: {
"error": {
"code": "ActivityLimitReached",
"message": "Failed to execute Skype backend request PostMessageRequest.",
"innerError": {
"request-id": "blahblahblah",
"date": "2018-04-30T18:39:45"
}
}
}

As you can see below, I back off new posts exponentially when the activity limit is reached, but, after a while the access token expires and the app needs to be restarted. I tried batching the requests, but I hit the limit sooner that way for some reason. I am currently playing around with increasing the expiration of the access token in Azure Ad, increasing the default expiration from 1 to 23 hours. I think the way to handle this is using the refresh token to get another access token, but this is beyond me so far. I'll keep looking into it. Hope this helps someone, and sorry if I'm just cluttering things up with this issue; I've never posted to github before and am not sure the proper forum for this sort of thing.

Hi,

Hi,
Microsoft changed the App Registrations.
ChannelSurfCLI is a "legacy" application which is no longer supported.
I receive the answer "403" forbidden when launching it after successful login.
When I recreate the app registration in the new registrations, the request body is missing either "client_assertion" or "client_secret"
I can create a client secret in the app, but adding this value to appsettings.json it doesn't change anything.
Could anyone please help?

I've run into a problem with this tool. I am able to run the program and connect to my azure tenant. However, when it gets to line 121's in program.cs it uses' Environment.Exit variable which im assuming is due to having a blank selectedTeamID.

I am wondering where i might have gone wrong to miss this variable.

I've run both commands

• dotnet run /path/to/channels.json
• dotnet run /path/to/slack/archive/myexport.zip (replace myexport.zip with your archive filename)

Both lead to the same result.

i am able to complete the below instructions

• Follow the instructions provided to sign in:
  • Start a web browser and go to https://aka.ms/devicelogin - we strongly suggest you use your web browser's "private mode".
  • Enter the security code provided in the command prompt
  • Consent to using ChannelSurfCli
  • Enter your O365 credentials.
  • Return to your command prompt

However, i do not see a way to complete the following

• Select the target Microsoft Team you want to create or re-create your channels into. You can also choose to create a new Microsoft Team.
• Go back to the Microsoft Team app and explore the channels you added!

I also stuck on this step. I already cleared for all step following manual but I have no idea what should I do after this to import my export slack data to Team.

Hi Guys, I am stuck at the place right after the authentication. I can successfully sign in in the command prompt. like below

“Let's get started! Sign in to Microsoft with your Teams credentials:
To sign in, use a web browser to open the page https://microsoft.com/devicelogin and enter the code *** to authenticate.
You've successfully signed in. Welcome ***”

Then nothing happens afterwards...
Any idea why?

The thing I am suspecting now is the permission to "read/write all groups". To get that permission, it needs grant by the admin of the organization...how do you guys get that...

I appreciate your help.

  - https://aka.ms/dotnet-download

I was able to fix this by downloading and installing the .NET Core 1.0.5 & 1.1.2 SDK 1.0.4 file from here.

After this point, I ran the command again, but this time I received the following errors. Any help with this would be greatly appreciated!

Welcome to Channel Surf!
This tool makes it easy to bulk create channels in an existing Microsoft Team.
All we need a Slack Team export ZIP file whose channels you wish to re-create.
Or, you can define new channels in a file called channels.json.

I've followed the steps provided through "Using ChannelSurfCli". When I run either command, I get back:

C:\Users\mine\source\repos\ChannelSurf>dotnet run C:\Powershell\Slack\channels.json
Couldn't find a project to run. Ensure a project exists in C:\Users\mine\source\repos\ChannelSurf, or pass the path to the project using --project.

I've double check and my build is successful. I'm not sure what I'm overlooking. I appreciate your help!

Hi,

when I try to start channelsurf, I get the following error message

Unhandled Exception: System.AggregateException: One or more errors occurred. (AADSTS7000218: The request body must contain the following parameter: 'client_assertion' or 'client_secret'.

What did I do wrong?

Many thanks for your help
