Upgrading ledgersmb 1.2.26 to svn master: upgrade to branches/1.3 first?

[Jeff Kowalczyk <..hidden..>]

Would like to migrate an existing ledgersmb 1.2.26 (svn branches/1.2 actually) 
database to 1.4 (svn master).

What is the recommended migration step chain for this operation? Do I migrate to 
svn branches/1.3 first, and then to master?

Or can I go straight from branches/1.2 to master?

Thanks,
Jeff
