I have a MailPoet integration on https://old_site.com/. We are currently redesigning the website and setting up a subdomain for this purpose: https://sub_domai.new_site.com/. My aim to migrate all MailPoet settings, lists, subscribers, newsletter designs, and other configurations to the new staging subdomain.
According to https://kb.mailpoet.com/article/377-how-to-migrate-mailpoet-database-tables I have import all of the table (41 tables) with *_mailpoet from https://old_site.com/. Then I have uploaded them to the https://sub_domai.new_site.com/ . Before upload those table I have renamed all of the existing table which was with *_mailpoet in the DB of https://sub_domai.new_site.com/ .
But, “MailPoet version update is in progress, please refresh the page in a minute.” showing in top of my dashboard after clicking on the Mailpoet menu. And Mailpoet menu page is disappeared now.
I have compared the Mailpoet version on both site. And noticed that there is an old version on the https://old_site.com/. That’s why I have replaced the updated version with that old version on https://sub_domai.new_site.com/ . But no luck.
Note: I did not import the csv file for subscriber on the https://sub_domai.new_site.com/ . I can not access the Mailpoet menu.
Can you help with this, please?
