You can create a version of your Product Template site at any time. At the very top of the Multi-tenant tab for the template you’ll see the CREATE A NEW VERSION section.
Creating a new version results in two things happening:
Since GIT is being used here, you need to make sure that you have committed all your changes using the COMMIT & PUSH button on the GIT tab BEFORE creating a new version.
Some things to keep in mind:
You can create a version at any time. As versions are created, they will be listed in the EXISTING VERSIONS section of the MULTI-TENANT tab.
For some operations (eg: Selling Site Subscriptions with WooCommerce), you will need to specify a default version. This is also called the PRODUCTION version.
The default version is the one that will be used in certain site creation operations if no other version is specified.
Creating a new version or setting a production/default version does not automatically upgrade existing tenants. All tenants remain on their existing version until you designate them for an upgrade.
If you do not upgrade your tenants, they will remain on the version that you designated at the time the tenant site was deployed.
After a version is created, it is a stand-alone site. You should back it up at least once using the WPCD backup option (or a backup plugin that is part of the template) and ensure that the backup is stored off-site. Or, if the template server is being backed up by your provider, that will suffice as well.
