License issues and version migration



our website was designed by our corporate office overseas. We have not been given any indications about the account info and general login credentials. So a few questions:

  1. We want to purchase a license to get support for our Jupiter theme. Our current version is 5.0.5 we but don’t know if it’s possible to purchase a license for that specific version or if we have to migrate to version 6

  2. If we have a child theme, are there risk if we migrate from our current version to the latest Jupiter version?
