hi @dabeecher,
I’m assuming you’re replacing the old website with the new one? and are you keeping the same database?
If you’re keeping the old database, upgrading to the newest version would be fine. If you’re upgrading from a version earlier than v6.0 you should create new forms, but aside from that everything will continue to work with the old data. The majority of their data is in Stripe, except for subscriptions that expire after a number of times, which the plugin keeps track of. If you keep the old data, best to keep it all even if you use new forms.
If you re not planning on keeping the old database around, old subscription unfortunately won’t show up in the plugin automatically; there’s no sync process in place. You could migrate the data (specifically the “wp_fullstripe_subscribers” table) which would at least populate the Transactions->Subscriptions view, though you should replace the “formName” value with the name of the new subscription form just to be on the safe side.
Not sure if they’re also using the Members Add-on? that would complicates things a bit more
@dabeecher i’m going to assume the migration went well, or at least that you have no more questions. You’re welcome to reach out on [email protected] as well if you do have more questions
