So My Plan is, with the Mix of V1 and V2 Chassis, rather than mess with Step Upgrades and what not is:

- Upgrade all of the Chassis with Brand New V2 Chassis
- Load Essential Edition R11.0 On all of the new chassis.
- Migrate Existing Licenses from ADI to PLDS

- For Centralized Voicemail, Do all the Remote Sites need Preferred Edition or just the main for Centralized Voicemail?
- To upgrade the Main Sites Voicemail Pro from R7.0 to R11.0, is there a Upgrade Licenses Required?
- Will all of the cards in the current chassis work with the New Chassis on R11.0?
- Will the DIG DCPx16 V2 Expansion Module upgrade and work on R11.0?
- I know the 5410 / 5420 / 1416 / 1408 are not supported on R11.0, however has anyone had success using them on R11.0? This might be the deal breaker if they will not work as they will need to upgrade around 150 phones.
