Hello,

I know that FB2.5 to F3.0 is possible :

First do backup under FB2.5 and after restore under FB3...

But I may not understand your problem : do you want to do an FB3 -> FB2.5 restore ?

IF yes I may presume this is impossible… I'm right ?

With best Regards,

Mickey

I'm trying to restore a FB 3 database to 2.5

Before fb3 backup,I copy from 2.5 gbak.exe to gbak2.exe into FB3 folder

then run

gbak2.exe -v -b "d:\db3.fdb" "d:\dbbk.gbk" -user SYSDBA -pass "mypass"

backup is done with no erorrs

I can restore it again to fb3 with no error but when I restore it to Fb2.5 I got this:

Starting restore. Current time: 12:25:06 PM

Invalid token.

invalid request BLR at offset 27.

BLR syntax error: expected valid BLR code at offset 28, encountered 210.

Exiting before completion due to errors.

Restore completed. Current time: 12:25:08 PM. Elapsed time: 00:00:01

restore is done from IBExpert

thanks
