Confluence migration

[venkatraj v.p.]

we are planning to migrate confluence to a new server. when we move the servers, can we install the latest confluence version in new server and upgrade it simultaneously. currently we are running 5.6 confluence and when we migrate the server can we install the latest confluence and perform a back up and restore.

2. we need to switch the confluence db from mysql to postgresql. will we be able to switch the db using xml backup without manually changing the db data structures. will we be able to do this when we migrate the servers and upgrade to latest confluence version

will this approach work .

Hi @venkatraj v.p.

I did a quick search in google and found the following

I would suggest a fairly bullet-proof mechanism:

1. Spin up a new instance of Confluence on a new server using a dev license.
2. Do a full-site export of the existing server
3. Import the full-site back up to the new server
4. Make needed changes for the plugins, base URL, etc.
5. Decommission the old server.
6. Move the production license to the new server.

The reasons I like this method are:

• It is straightforward
• Because you are basically writing the backup to the new database, it is independent of OS and DB engine. So if you want to migrate from Centos 6 to 7 or other distro, and/or Mysql to Postgres, this makes it easy.
• Errors are usually easier to recover from since you are not trying move the database itself.
• You not migrating any configuration issues over to the new server, especially an issue if you have done several inplace Confluence upgrades.

Hi Dave,
