i applied that approach when migrating ase12.5 to ase15- try it
1-Quiesce the database to a manifest file
quiesce database for_upgrd hold testdb
for external: dump to “d:\data\db_manifest.mfst” with override
2-Copy the devices using disk copy commands, or file explorer to the new destinatin.
3- When the device copy is finished, release the quiesce by a SQL statement similar to:
quiesce database for_upgrd release
4- If this is the final upgrade , shutdown old ASE to prevent further changes.
5- Move the device copies to the new host machine and mount them using mount command(for more detail see ref manual).
i got that approach from one of sybase seminars
pls , for all using ASE15 , try ownloading the new EBF bug fix from sybase download site. there is a new one at june 2006, and upgrade ase15.
