Even we are planning to migrate from JBPM 3.0 to 3.2.
Can anyone please provide the detailed steps to migrate from JBPM 3.0 to 3.2?
I also would want to know that if we migrate to JBPM3.2, will it have any affect on the existing customers data?How the existing data will be inserted in the newly created columns and tables?

upto 3.1 the migration has received (to) little attention. From 3.1 on supporting migration is very important. So unfortunately I (personally) have little info on migrating from 3.0 to 3.2.

3.1 to 3.2 is supported very wel by using migrationscripts for the db.

Ok, I give and sorry if they are in an obvious place, but where are these migration scripts that I have seen mentioned? I have found plenty of creation scripts, but nothing going from 3.0 -> 3.1 or 3.1 ->3.2? Thanks in advance for any direction.

3.0 -> 3.1 Not Available
3.1 -> 3.2 is in the source. Look for generate.schema.update.bat
