How to migrate the database from Progress 8.x to Progress 9.x

1)  Backup the database.

2) If the database is not a version 8 database, first convert it to version 8 by either using the conversion utility (Conv78 for Progress 7.x) or using Dump and Load.

3) If the database is single volume, you will need to convert it to a multi-volume database in Progress 8. It can be done using prostrct convert <db-name> from Progress 8.

4) Truncate the BI file. It can be done using proutil <db-name> -C truncate bi from Progress 8.

5) Run proutil <db-name> -C conv89 from Progress 9. This should take under 5 minute regardless of database size.

6) Backup the database.

7) Add areas to the database.

8) Move the data from area 6 to the areas you've just explicitly created.

Starting from 9.1D, you may use the option "mvsch" of proutil to truncate the schema area.
