 I have a large Firebird 2.5 DB (a couple of tables have few millions

 Is there a way to do efficiently this kind of conversion? (preferably
 not using a intermediate text sql dump, that would not applicable

 I'm using Firebird on a linux machine, and I really like to do the job
 using a bash script,
 but I can fallback also using a remote Windows pc.

 Thanks for any suggestions.

I don't know if there is a faster way... But this one would be a secure 
and very easy way:


1.) Extract metadata from the source database (isql -x)
2.) Change the definition of the domains and/or fields to the desired 
charset

3.) Create a new database with the corrected script
4.) Use IBDatapump (or any other datapump tool) to transfer the data

I don't know the size of your database, but I doubt it will take days to 
transfer it.


To speed up the process, turn forced writes off, try to keep the 
source/destination database on diferent disks and use local/embedded 
connection


see you !
