Export data as XML and import it back after pointing to new DB, you should be fine. Regarding plugins, it depends on implementation but most of them should be using internal database or active object which are taken care during export/import. Neverthless, I suggest a test migration.


your suggection's are always helpful to me.

but my db size is 90 gb.

do i need to update plugin's with db dump's.

awaiting for your suggection's.

Oops, 90GB is huge. I guess you have the attachments stored in DB? You might have to check if there are any DB tools available for migrating data from Oracle to Postgres. Unfortunately, I am not an expert to recommend one!

@jobin can u please suggest what could be plugin level change's. need to do.

Hi Tousif,

I also agree with Jubin answer ;).

If you need a guide for that migration you can check the Migrating to Another Database KB :).

Thanks and Regards,

@deividi thank's.

my db size around 90 gb.

dba will convert to postgress no prob's

we got some custom plugin's which are working with oracle db.

when moving to postgress what change's you suggest at plugin level.


tousif shaikh.

Not a problem :).

As Jobin said, the best way is to set up a test Instance.

Export data as XML and then after you set up a new confluence installation in a test Env (same version as Prod) with Postegres DB, just Import the XML.

Since all the plugin's you upload (including your Custom PlugIns) on Confluence are saved on the PLUGIN DATA table at the DB, after the import on the test instance they will be there for you to test.

Thanks and Regards,
