Hi Amy!
Excellent question. Please review this handy guide on moving license keys within your account.
I’m unsure of the constant updates and subscription message you’re receiving. We typically aim to only release a maintenance release once every two weeks (sooner for hotfixes that are occasionally needed) and a major release about 4 times a year.
If it continues to be a problem, please send us more information so that we can look into this further with you or at least help point you in the right direction. I don’t want to default and say it’s due to the migration, but I’m wondering if there is something going on with your WordPress install or host that may be causing this issue that may have occurred during the migration.
Please let me know if this helps answer your question! 🙂
Have a great day!
