I just emailed you and Shehroz about this but I'll post on the thread for everyone else.
There's a new version of the ProcessBook support tool that will be publicly released sometime in the near future that can handle AF objects. The current latest release (3.2) cannot do any AF renaming.
Until it's officially released, you can contact tech support to obtain the install kit for the alpha release.
I have found the solution myself. If you have developed the PI ProcessBook / PI AF Project on ABC PI Server (in-house) & you want to deploy it on XYZ PI Server (plant)
Just add alias ABC in XYZ PI Server (plant) both in PI SDK & PI AF.
you project backup will successfully run on new PI Server.
