move confluence to another server

[Jim Nilsen]

This question is in reference to Atlassian Documentation: Running Confluence in a Virtualised Environment

Need advice on how to move confluence to another vm.

[Bill Bailey]

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.

How to obtain dev license to install new server with external database?

What is the full-site export? You mean database export to xml?

[Roman Kirilenko]

This way is suitable only for small instances. If you have a really large installation you will get a lot of problems with this way of migration.

[Nic Brough -Adaptavist-]

I'd agree with Roman here.  For large installations, you definitely want a copy of the home directory and a copy of the database after shutting the system down. 

Export/import is for small systems, or for changing the database if you must.

[Bill Bailey]

Well small, maybe. He didn't state how large his is. I have used it without issues on instances of 1000 to 2000 pages.

And with full-site export, I mean from the backup and restore tab in the Confluence admin console.

[Roman Kirilenko]

You didn't specify what OS and DB you're using on source and destination servers. In general, you can start from here.

Please feel free to ask any additional questions if you need.

[Bahman Sharzad]

It's from ubuntu with postgresql and move it to same os and database.

[Alexander]

Lars, could you send your script to me. Please

"advice" is pretty open-ended.  All I can really advise is that you build the new server, install Confluence on it empty, do some testing, then plan and test a migration on to it using a copy or export of your current system (as suggested in the documentation), and then plan to do it for production when the testing all passes.
