There are occassions when PeopleSoft doesnt provide a direct upgrade path from one version to another i.e. 7.5 to 8.8 or 8.3 to 9.0. PeopleSoft suggests that such installations require two upgrades in one go, i.e. from 7.5 to 8.3 and 8.3 to 8.8 or 8.3 to 8.9 and 8.9 to 9.0 in my examples. However, what PeopleSoft doesnt warn you about any special care when performing such upgrades. All PeopleSoft provides is the documentation to upgrade from one version to another.
However, from experience, we have found this to be a process that requires special attention. As you are aware that upgrades require 2 passes i.e. first 'initial-upgrade', using a copy of live database, and then 'move to live'. When you perform the 2nd pass i.e. 'move to live' upgrade, it requires the copy of database on which you performed the 'initial' pass. Now consider a situation where you performed 'initial' upgrade on a 7.5 database to move to 8.3 and then you performed 'initial' pass to upgrade the same database to 8.8. When you come to performing you 'move to live' pass from 7.5 to 8.3, you dont have a copy of database that is on version 8.3.
Therefore, it is quite important that you keep a copy of database, in working order, before moving to the next version.
Also, sometimes it may be easier to re-implement rather than upgrading 2 versions. However, it all depends on the usage of PeopleSoft and the complexity involved.
