Hi vino,

Thank you for your question.

If the migration has been completed, message flow and Exchange services are running without any problems. And it has powered off 15 days by your state, we could uninstall Exchange 2010 directly by control pane.

If there are any issues after we uninstall it, welcome to our forum to ask for help.

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,

Jim
