Hi guys.
We needed to upgrade a very custom EE site for a client.
We took a copy of the site onto a new EC2 server to test upgrading ExpressionEngine. After months of work we got it signed off to be done to the production sever.
I’m in the situation now where I have the signed off and upgraded code (for EE 2.7.3) that I want to deploy on a new EC2 server (which will become the live one) but the database we’ll need to use is a snapshot of the current live one, which is EE 2.3.1.
How can I upgrade the 2.3.1 database to match the 2.7.3 code?
I have tried using the 2.7.3 installer, but it just says “You are now running the most current version of ExpressionEngine!”, but the database is still the old 2.3.1 one. I almost wonder if there’s a version number stored somewhere in the code that is stopping it running some migrations.
Thanks!
