Want to migrate to Modern Public Folders on Exchange Server 2013, 2016, or Exchange Online (O365)? Start preparing now. I have created a quick list, below, of areas to fix. These steps are based on my numerous Exchange Server 2010 Public Folder migrations. Fixing all the errors below will lower the amount of PF migration redos/reruns. You will have at least one rerun/redo (due to errors) for your PF migration - so plan on it. Lets first start with a few links to review for the Public Folder Migration Steps:
