We are happy to announce Organization Configuration Transfer (OCT) - V2, which includes updates to OCT-Phase 1 that was launched earlier this year. OCT-V2 further reduces the manual work that admins are required to do once the hybrid setup is complete. OCT-V2 is now available as part of the Hybrid Configuration Wizard (HCW).
What does OCT-V2 include?
OCT-V2 not only copies the organization policy objects from on-premises to Exchange Online (EXO), but also updates the values in EXO with the values from on-premises. Seven additional objects have been added to OCT as part of V2. The list of objects considered in OCT so far are:
OCT (available since June 2018)
Active Sync Mailbox Policy
Mobile Device Mailbox Policy
OWA Mailbox Policy
Retention Policy Tag
OCT-V2 (available now)
Active Sync Device Access Rule
Active Sync Organization Settings
Malware Filter Policy
Policy Tip Config
If object values are updated on-premises after they are moved to EXO, admins can re-run OCT to copy over the updated values from on-premises to EXO. Admins will continue to control the process of keeping the objects in sync but with reduced effort by using OCT.
How is V2 different from the initial version of OCT that was launched in June 2018?
Phase 1 of OCT dealt only with copying objects from on-premises to EXO. However, it did not edit/update the parameters in EXO. As part of V2, if an object with the same name already exists in both on-premises and EXO, admins can now choose to either overwrite the values of the objects in EXO or keep them as is. A rollback script with values of the objects prior to the update in EXO will be available to admins in the log folder.
What are the Exchange Server Versions supported?
The supported versions are Exchange Server 2019, 2016, 2013 and 2010. OCT-V2 requires the latest cumulative update or update roll-up available for the version of Exchange you have installed in the on-premises organization. If you cannot install the latest cumulative update or update roll-up, the immediate previous release is also supported. Older cumulative updates or update roll-ups are not supported.
