My websites became inaccessible after the license expiry. How to revert to openlitespeed?

I just tried the Ent Litespeed. But now after 15 days all of my websites became inaccessible. How can I revert back to Open Litespeed again?

Thank you

You need to spin new server and make sure you install OLS.
You can easily restore sites with remote backup option, but all other server setting need to be done manually.

Get a new server with ols move sites there
