I'm trying to transfer a Tigase XMPP server from an Ubuntu VPS to a CentOS VPS. Unfortunately there isn't any official documentation available and I need to experiment in order to preserve all of the current data.
What I've tried so far:
I. Copy the sql database
- Install the same version of Tigase to the new server.
- Dump Tigase's mysql database table from the old server and import it to the new one with --ignore option
Result - server runs and I can create new users, but old users can't log in. I confirmed that user passwords have been correctly copied to the new database and that both databases use the same hashing key.
II. Move the whole Tigase directory and the database
- Tar zipped the Tigase directory from the old server and the database
- Extracted them to the new server and overwrote the database to the new server.
Result - Tigase doesn't start and returns various runtime and connection errors.
Question
Is there a way to transfer (export/import) the Tigase user data from one server to another?
Update
I found some article concerning importing data, however it's very old-dated: http://www.tigase.org/content/importing-user-data I think the database structure is different, for example I can't find information about user's rosters, nicks, existing MUCs etc, which I would like to preserve.
