Our current DB version and release is 14.00.04.03 on SLES 11.

My company has three systems: DEV, DR and PRD.

We are going to apply patches to these 3 systems and the new release is going to be slightly higher, 14.00.05.XX.

The order of applying patches will be DEV, DR and PRD and several weeks between them for user tests.

What if there is a disaster after applying patches to DEV and DR. Is When we restore PRD data to DR box is it going to be any issue because of different patch levels?

After upgrading to 14 we haven't practiced DR.

Thank you,

James Park
Database Specialist
