I manage a self hosted Rocketchat installation. Rocketchat is being used for internal chat communication.
Due to several issues i face with Rocketchat, i want to switch to Nextcloud Talk. And in the future Nextcloud will be used for additional purposes like File Sharing.
At Rocketchat i have important data. And many times i go back to chat history in order to find several information.
At Rocketchat i have direct messages with other parties and chats with more than one parties.
Is there any way to migrate all chat history from Rocketchat to Nextcloud talk?
That’s an issue you most likely also will experience with Talk, at least there are multiple threads in the forums with people having issues receiving notifications reliably, especially on mobile devices. It’s possible that it has improved lately or maybe there are ways around it, but I suggest to test this extensively before you migrate all users over to Talk.
Afaik there is none. Your best bet is probably to keep Rocket.Chat up and running and put all chat rooms into read only mode, if possible. Or maybe you can use Matterbridge in order to connect it to Nextcloud Talk.
