Hello Community,
In our production there are two Confluence instances. We are planning to migrate or consolidate the two instances and make it as one. I need tips and suggestion for how to achieve this migration.
Note: we got the task to migrate all the data from Instance A to instance B. Currently there are no non-prod environments setup.
Instance A -
Current Confluence Version - V 6.4.1
Operating System- Windows Server 2012 R3
Application Server - Apache Tomcat V 8.0.43
Database - H2 database
Database Version - V 1.3.176
Database Driver Version - V 1.3.176
Java Version - V 1.8.0_131
JVM Version - V 1.8
Instance B-
Current Confluence Version - V 7.1.3.7
Operating System- Linux 5.15.0-1034-azure ( Datacenter with HA )
Application Server - Apache Tomcat V 9.0.63
Database - PostgreSQL database
Database Version - V 14.7
Database Driver Version - V 42.2.18
Java Version - V 11.0.14.1
JVM Version - V 11
Hello @niranjan
Ordinarily I'd say that you could export your spaces on Instance A as XML (backup) and then import them into Instance B.
According to these docs here, you should be able to import the XML zip file created on Instance A into Instance B.
Good luck!
Hello @Robert Wen_ReleaseTEAM_
Thank you for the solution. If we do XML import on instance B does the existing data on the instance B gets wiped out and imported data will only be there ? Also how to import the attachments, images, add-ons which are there on instance A ? please suggest.
Thanks

Take a look at the following knowledgebase article
https://confluence.atlassian.com/conf64/restoring-a-space-936511534.html
It should get everything you need for the space (except users and groups, I believe)
I also don't think it will overwrite the data on Instance B.
