before starting the activity you have to create one public folder on server,

For the receive connectors, yes create any additional/custom ones on the new server and direct those hosts that use them to the new server (hopefully they’ve been using a DNS alias for this so you can just update that one DNS alias. If not, consider doing that from this point forward

You’ll also need to look at any external URLs for services such as OWA, ActiveSync, and how you’ve published those to the internet

First start SQL service in a Single User Mode.

  • Stop the SQL services
