I am going to upgrade my IDM environment (consisting of an AD connector,
an eDir-to-eDir connector, a JDBC connector, and a user application that
mostly just does password changes) from IDM to IDM 4.6. With
previous migrations, I have done the following:

1. deploy new vault servers and add them to the eDir tree
2. Install new version of IDM on the new vault servers
3. Use Designer to migrate the connectors to the new vault servers
4. Retire the old servers

Will this work when going from IDM 4.0.2 running eDir 8.8.8 SP5 to IDM
4.6 running eDirectory 9, or do I need to migrate to IDM 4.5 first?
