Upgrade from server edition to cloud edition

Hi,

I am currently using server edition. I would like to upgrade it to cloud edition. Kindly outline the steps

Purchase a Cloud licence

Backup your business(es) on the server
Import your business(es) into the Cloud edition

You get a 7-day free trial so that you could backup & import and check that everything was copied before the purchase of the Cloud edition license

What version is the Server edition?

version 21.7.38
