Migrating Open fire from 3.10.2 to 4.2.3 for windows server

hi,

Any one Migrating the Open fire from 3.10.2 to 4.2.3 for windows server latest version please help me.

You should do backups and prepare for breaking changes as a lot has changed beteen these versions. I would not update to the latest version at once. You could install newer vetsions one bu one from here

Also read about windows service changes here http://download.igniterealtime.org/openfire/docs/latest/documentation/install-guide.html as Openfire is installing service automatically since 4.1.5. If you have service using, you should stop it before every installation.
