We are considering moving from 1.5x to 2.5x. 95% of our user base is using FB 
embedded (using Delphi and IBO) . We have a few thousand installs on Windows 
and it could be quite painful if this doesn't go smoothly--like sinking a boat 
in a storm.

We have a few questions:

1) It testing, it looks like we need to backup the FB 1.5 database and restore 
it with the new data structure. Correct? Otherwise I get "[DB] is not a valid 
database

2) If we are using FB embedded, do we have to backup with the 1.5 and then 
restore with 2.5, or can we backup and restore with 2.5? I tried with 2.5 to 
backup but get an exception saying it is not a valid DB structure. This would 
be an application has to be installed that will backup the 1.5 and then the new 
application could restore to 2.5. 
 

3) Is there anything we should be aware of?

Thanks,

Ed Dressel
