Hello, We are moving sharepoint portals from one server to the other. What would be the best practice in this case? Will back up and restore of web app work? Thanks in advance.

HI, You can use backup restore for site collections. I would suggets you to take DB backups of your content DBs. Create new farm and attach these there. make sure you deploy all customized functionality in the new farm as well. I hope this will help you outThanks, Rahul Rashu
