A discord bot for copying messages between guilds

discord-transfer

A discord bot for copying messages between guilds

Current version: v3.1.0

How to use ?

Download the JAR from the releases page.

Pre-requisites

Discord bot token

1. Create an application on Discord's developer portal: https://discord.com/developers/applications/
2. Create a bot for this application
3. Enable the MESSAGE CONTENT privileged gateway intent.
4. Copy the bot token and pass it to the application via the DISCORD_TOKEN environment variable

Invite the bot in guilds

In order for the bot to migrate messages it needs to be invited in both the source and destination guild, to do so you can use the following URL by replacing in your application ID (which can be found on the Discord developer portal)

https://discord.com/oauth2/authorize?client_id=<CLIENT-ID>&scope=bot

Launching

Pass the Discord bot token via environment variables.

• On linux and macOS open a terminal (bash) and simply prefix your command with the token as such:

DISCORD_TOKEN="MY_TOKEN_HERE" java -jar discord-transfer.jar [arguments...]

• On Windows you can use powershell. Define your environment variable and then run the program:

$env:DISCORD_TOKEN="MY_BOT_TOKEN_HERE"
java -jar discord-transfer.jar [arguments...]

The bot behaviour depends on the action you select.

java -jar discord-transfer.jar <action> [options...] [arguments...]

In most cases you'll probably want to use the migrate action to transfer messages, but there is also the clean action that removes the reactions used to mark migrated messages

migrate action

java -jar discord-transfer.jar migrate [options...] <source> <destination>

The migrate action takes 2 arguments:

1. The Discord ID (Snowflake) of the source Guild (the one you want to copy messages from)
2. The Discord ID of the destination Guild (the one in which messages will be copied)

There are also options to customize the migration behavior:

• --include-channel: Specify channels that should be migrated, it's category will automatically be created if missing, expects a Discord channel ID
• --category: Specify specific channel categories to migrate, expects a Discord category ID
• --skip-channel: Specify channels that should not be migrated, expects a Discord channel ID
• --text-only: Will only migrate text channels (skips voice channel creation)
• --after: Only migrate messages after the give date (format ISO-8601, ex: 1997−07−16T19:20:30,451Z)
• --delay: Add a delay between each message migration

Example: java -jar discord-transfer.jar migrate 123456789 987654321 --skip-channel 741852963

clean action

java -jar discord-transfer.jar clean [options...] <server>

The clean action takes a single argument, the Discord ID (Snowflake) of the Guild you want to clean reactions from.

About

This bot uses Discord4J as a bot library.

discord-transfer's Issues

Thread Functionality

Out of curiosity: do you plan to update this tool at any point to be able to export threads as well? This tool is incredibly useful for archiving channels in servers where old channels are no longer used, but viewing the old channels is still desired - but since threads were added after your most recent update, it doesn't recognize them at all.

Feature Request: "--include-channel" option

Sometimes, I want to migrate a singular channel from a category that that has 10+ channels in it. The existing --skip-channel option works great, but it's a bit tedious to specify the 9+ channels I don't want to migrate. It would be convenient if instead there was an --include-channel option that was mutually exclusive with the --skip-channel option that allowed me to specify just the one channel I wanted.

Feature Request: Start Date Argument

Fully migrating channels with an extensive message history (100,000+ messages) can take several days to complete. Sometimes, the bot will terminate partway through the migration process with "connection closed" errors. This isn't a big deal since the bot flags migrated messages with a reaction and will pickup where it left off once restarted. However, it seems to start its scan for unflagged messages at the beginning of each channel's history, meaning that sometimes it will scan tens of thousands of messages just to reach where it died. It would be nice if there was an optional --startdate/--date/etc parameter that would allow specification of where the bot should start scanning for messages.

Error: Source was empty

Getting an error when I tried to migrate. Here's the stack trace. I'm sure the source was not empty, there are valid categories and channels that exist so I'm not sure why it's giving that error.

java.lang.UnsupportedOperationException error when trying to migrate channels on server with a forum channel

I'm trying to migrate some old channels from one server to another. The channel category that I would like to migrate is pretty simple: it has 3 unique text channels and none of those channels have any threads. Elsewhere on the server, in a totally different channel category, we have one forum channel. When I run the migrate command, I get the following error:

java.lang.UnsupportedOperationException: Unknown Value: ChannelData{id=1027017741011525772, type=15, guildId=Possible{153767654270697473}, position=Possible{181}, permissionOverwrites=[OverwriteData{id=1017145521091133590, type=role, allow=3072, deny=0}, OverwriteData{id=193554506280206336, type=role, allow=3072, deny=0}, OverwriteData{id=1017145414933299330, type=role, allow=3072, deny=0}, OverwriteData{id=153767654270697473, type=role, allow=0, deny=1051648}], name=Possible{healer-forum-rp}, topic=Possible{Optional.empty}, nsfw=Possible{false}, lastMessageId=Possible{Optional[1035459503480639558]}, bitrate=Possible.absent, userLimit=Possible.absent, rateLimitPerUser=Possible{0}, recipients=null, icon=Possible.absent, ownerId=Possible.absent, applicationId=Possible.absent, parentId=Possible{Optional[1017143577773609011]}, lastPinTimestamp=Possible.absent, rtcRegion=Possible.absent, videoQualityMode=Possible.absent}

While I'm not 100% certain and don't have a secondary server to test with, I suspect that the forum channel is the issue because it's called out in by name in the name=Possible{healer-forum-rp} element and forum channels are a relatively new feature overall.

how to add the discord token

g'evening!

"Copy the bot token and pass it to the application via the DISCORD_TOKEN environment variable"

the question is - HOW?

when trying to run this program in the console, there is no prompt asking to input the value that would be ascribed to that "token" variable.
inside the code, that variable does not have a setter in the code.
inputting the token's value as a hard coded variable value also does not work because token is a string, and assigning a long set of numbers that is the discord token directly to it leads to a parsing error "java.lang.NumberFormatException: For input string: "?N8?N??^x?v??"".
you have previously mentioned to use $env:DISCORD_TOKEN="MY_BOT_TOKEN_HERE" prior to writing the terminal command java -jar [...] but this $env: line is not a valid terminal command, see below:

i tried running the jar - doesnt work, says unsupported binary file. i tried opening in JDK, also no success. tweaking the java file by hardcoding the token value there and exporting to jar does not work either.

when the app did not work, it said to type "help" for help, but that's also wrong because help is not a correct terminal command, and when this program runs in the JDK console, it is "read only" so you can't type anything (i.e. "help") to get any help.

what was the design idea, how is this supposed to work with this variable value insertion? how could i make it work? or is it perhaps designed to only work on linux and that's it?

A small tutorial would be nice!

Hi,
I have seen this project (?) and I want to use it on my servers. But I have no experience with Java before. So a short tutorial in the readme would be very helpful.
Thanks!

messages no longer copy after toggle on the message content intent to "on"

hello

so previously the messages all copied, but empty (all info BUT the message itself was copied - empty messages, just timestamps and nicknames), to which you advised to set the "message content intent" toggle in bot settings to "on":

this however makes the messages just to stop being copied at all:

what else could i be doing wrong here?

Migration finished successfully (0 messages)

Hi, Amazing app, I'm trying to migrate a server and this is just what I needed!ç
I'm getting the message "Migration finished successfully (0 messages)" even though the channels in my source Discord server are not empy. Here is the log I get, Please note I removed all private information before pasting it here:

Any thoughts? thanks in advance

Include Hour/Minute timestamps

First of all, thank you for the bot!

This is a small feature request. For the sake of archiving a server of ours, I'd also like to see the HH:MM timestamp as well aside from the date.

Failing Link in Usernames for Transferred Messages

When the bot transfers messages from one server to another, the usernames on the messages are clickable links - but when clicking them, I receive a "You don't have access to this link" message.

Do you know why this might be, or what the link is supposed to direct to?

Where to import the Discord token?

Hi, don't really know where to import the bot token. When I run the code it says "MISSING DISCORD_TOKEN Could you please give me some assistance? Thanks

When the bot is migrating a channel and tries to process a message that already has the maximum number of reactions (20 unique emotes) added to it, it crashes with the following error message:

I'd probably expect the bot to write a warning message to the log and just skip adding the "processed" reaction to this particular message.

Bot stops working after a large number of messages in a channel. It simply won't work regardless of how many times I tried. The bot also take more time to load the more messages it have transferred.

How do you add the DISCORD_TOKEN?

Hi there. I've got everything set, but cannot figure out how to feed the bot token as an environmental variable for the app. Is this done via the command line? Every time I've tried it returns: Missing arguments (action, guildA, guildB)

"Copy the bot token and pass it to the application via the DISCORD_TOKEN environment variable"
I have the token, how do I get it into the app?

Do I create a file? Or run a command like: java -jar discord-transfer.jar DISCORD_TOKEN ansdfnasdnANSFNASDfASDNF

Thank you

Adapt arguments to action

As presented in #14 the clean action still takes 2 arguments (src and dest) even though it only uses the first. We could get rid of the second one for this action.

Guild ID too long

I tried hardcoding the values, but I'm observing an error that the integer values are too long... am I missing something?

413 Payload Too Large with response {code=40005, message=Request entity too large}

@BilliAlpha
Thank you for this great bot, but I seem to have a problem with it that probably doesn't deserve this but I don't know what else can I try to do. Bot seems to get stuck with 413 error every time I try to migrate and after failing to find a solution to the problem online I'm only left with asking you. Sorry in advance for this sounding very rude but English is not my first language so I don't know how to make this sound polite.
This is what it tells me:

Message content not copied

Hi. Thanks for this tool! I tried to migrate one channel, and the tool succesfully retirieved all message from it. Unfortunetly, He only get the date and author :

Did I miss something ?
