We've been having many issues during our migration for Exchange 2007 SP3 CU14 to Exchange 2013 CU6 with interim update to resolve the DB dismounting and EAS proxy issues.
Our environment consists of a small organisation, ie one 2007 exchange and one Exchange 2013.
I need to plan for the removal of the legacy public folders, of which there is only one in use. I will even move this to a shared mailbox rather than worry about migrating to a modern PF. Given that there is only one PF in use could I simply:
1) Delete the legacy PF's after checking the important one is OK as a shared mailbox
2) Remove the Public folder database using these guidlines:
3) Finally go ahead and decommission Exchange 2007
With all the research I have done many articles seem to be older than regarding CU6 era information or talking about migrating them first which I don't think is necessary in our case.
