Migrating from V8i to CONNECT products

I am developing a migration plan to move to CONNECT Edition products.  My organization is currently running:

• MicroStation V8i SS-3 08.11.09.459
• ProjectWise Client V8i SS-4 08.11.11.123
• PW Integration Server V8i SS-4 08.11.11.123
• PW InterPlot Organizer V8i SS-4 08.11.11.56
• Various V8i apps (InRoads,OpenPlant,AECOsim,ProStructures)

After doing my development and testing, I would anticipate starting the actual move in early 2017.  Given that timeframe, are there any compatibility problems with migrating in the following order.:

• Upgrade all users to Mstn CONNECT and PW Client CONNECT; do this user-by-user while production is in progress.
• Upgrade PW Integration Server to CONNECT version.
• Upgrade PW IPlot Organizer to ???
• Upgrade apps to CONNECT versions as they become available.
