Thank you for all the help -- migration involved zero hassles
I did get one error
SQL 2.1.0.8 1064 in INSERT INTO `ps_configuration`(`name`, `value`, `date_add`, `date_upd`) SELECT 'TB_MAIL_SUBJECT_TEMPLATE', '[{shop_name}] {subject}', NOW(), NOW() WHERE ( SELECT COUNT(*) FROM `ps_configuration` WHERE `name` = 'TB_MAIL_SUBJECT_TEMPLATE' ) = 0: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'WHERE ( SELECT COUNT(*) FROM `ps_configuration` WHERE `name` = 'TB_M' at line 3
but the store seems to be working fine so I don't think it was something critical.
I do have an issue that pretty urls doesn't work but that issue was present before migration. I moved the PrestaShop store to a new server as part of the update process and I believe I must have made an error with Apache configuration that is preventing redirects. That is on me and has zero to do with migration. Migration was ridiculously easy and I look forward to building a better store on 30 Bees
