In our case URL of website stays the same, as we are not using plugin for migration but doing that using wp cli.
So, in details:
Provided test case by support:
site1: valid key for site1 and domain name site1
site2: valid key for site1 and domain name site2 (including domain name in wp_options, etc)
our case is:
site1: valid key and domain name site1
site2: valid key for site1 and domain name still site1 in all settings, except web server, which is configured to site2 and request done through wp cli (even without any parameters)
Can you please, give a look at the related ticket and let me know if your issue is related? Just asking, because if so, it is something already escalated to our second level support and it is under investigation. For your case, do you see the issue if you re-register your migrated website with a new valid key? I understand you are using a wp-cli approach, however, as said the issue with the invalid key might be related and I would need to wait the result of our investigation from our second level support team.
Please, let me know these details, so, we can move forward to a resolution. Have a nice day.
Thank you for the confirmation. I checked our issue tracker and noticed the issue is now escalated to our developers for a permanent fix. I will let you know as soon as I have further details. For now, as a workaround, please, register your migrated website with a new valid key.
Thank you for your patience and understanding. Have a nice day.
