where is find docs of jira/confluence migration from server to data center

[Bill tang]

Hello,

 We are running Jira/confluence/crowd on self-installed servers with many users licenses, and in near future, we plan to migrate these systems to data center. So how to migrate existing systems data is a challege confronted us. Are there some guidline or migration docs regarding  jira/confluence migration from self-hosted server to data center? 

thanks

Bill

Hi @Bill tang 

For Jira you can find some entry documentation here: Jira: Server to DC 

Here for Confluence: Confluence: Server to DC 

And for Crowd as well: Crowd: Server to DC 

Best regards

Thanks your quick response.  To my knowledge, while running Jira on a self-hosted server, we will setup a new jira DC. After this new jira DC is built, we are facing  how to migrate existing jira user data such as jira, configuration stored in DB and file systems to newly established DC?   After quickly browsing these pages,  I don't find more concrete pages on how to migrate existing user jira/conflucen data from server to DC. Any suggestions?

Not soo easy to answer. It really depends on your current environment and setup. But usually the home directory needs to be split up. One shared where the user data is stored such as attachments has to be mounted somewhere else. Usually on a shared/network directory. The other home directly is per node, this will store your  node logs, cache etc..

Actually there is no need to "really" migrate any data. You have to change the infrastructure to be supported (like shared home directory and shared database server). 

If you're running DC on a single node at the beginning, it would also ok to have the home directly just on a different location, as the setup within the UI will claim. Testing this on a test instance should be the way to go. 

Without knowing every detail about your current setup and the DC Setup you would like to implement, this is only a very rough guideline. 

So I would recommend to create a copy of one of your application and change the infrastructure on this playground. 

If this is not working, you can also ask any of the Atlassian partners to assist in here.

OK, got it.  Is it also necessary to backup and restore jira data stored in mysql when migrating to DC ?  I find a page  https://confluence.atlassian.com/adminjiraserver087/backing-up-data-998872458.html

Backing up is always recommended, before going anything on the database, just in case something went wrong. 

If you still using the same database, there is no need to restore the data. If you switch the database e.g. from a local MySQL database server to a scaled one within a (private) cloud or your own racks, you have to restore the data of cause on the target database. If it's the same DB server it is usually not a big deal. 

The linked article, it is about backups in general, not specific for migrations to DC. 

But as mentioned, it always depends on your specific infrastructure.
