Restore on different version

Hi, I was asked to try a restore for a client on version 7.31, using a 7.30 backup. I told them that this was not supported, but they insisted that I do the restore and prove that it doesn't work. So I set up a database on another machine, took the 7.30 backup (that was done on an HP opsys) and tried to restore it on the 7.31 database (that is on a Solaris opsys), with the following result: Continue restore? (y/n)y Do you want to back up the logs? (y/n)n Physical restore failed - buc_fe.c : Archive API processing failed at line 740 for msgtype Program over. My manager is still not happy that this doesn't work, and says I didn't try hard enough. How can I respond to this - seriously ?

How can I respond to this - seriously It doesn't work. The reserved page structure etc are different. You can usually restore between the UC and FC releases of the same version. Sometimes you can restore between close releases, eg 9.40FC% to FC4, although in the recent versions you get a warning at the start. These releases are too different.
