Hi @PulseI

Are you running CCMA on a H2 database? This isn't recommended and you should be doing the testing and production migration on an external database like PostgreSQL.

Regards,
James.

No. Here is our DB setup. 

[James Richards]

What version of Confluence are you running? If you have version 8.4.20 of PostgreSQL then that's not going to work.

The minimum version of Confluence that runs Confluence Cloud Migration Assistant is 5.10.0, and it has a minimum version of PostgreSQL of 9.2

See

• https://confluence.atlassian.com/conf510/supported-platforms-829078376.html

Please upgrade your database to the minimum supported version for your version of Confluence and try again.

James.
