Prepare Developers for the Upgrade
To prepare developers for the upgrade, do the following.
Back up the development database.
Verify that all developers have checked in their projects and that all projects are unlocked.
Verify that all developers have disconnected from the database. The only open account must be the account that is performing the upgrade.
Install the new version of Siebel Tools on development workstations.
Note: Keep at least one copy of the previous version of Siebel Tools. You will need it to perform repository operations before the repository merge.
