Will different versions work with the same database?
Permalink
This is probably a silly question. I've got a site that is a few versions back. I want to change server and install the latest concrete as I'm updating the theme. Will a new version of concrete work with an old versions database?
You should upgrade sequentially from the last stable release for each version,
So, if you are on an old 5.4.x.x version, upgrade to the latest 5.4 version release which is 5.4.2.2,
Then upgrade to the latest 5.5 release which is 5.5.2.1
Then upgrade to the latest 5.6 release which is 5.6.1.2 (current)
So, if you are on an old 5.4.x.x version, upgrade to the latest 5.4 version release which is 5.4.2.2,

Then upgrade to the latest 5.6 release which is 5.6.1.2 (current)
What you should do instead, is move your existing site and database and upgrade it to the latest version - the upgrade process will make any required database changes for you. I've updated lots of old sites to 5.6.x without any issues/
If you are on 5.4.something, upgrade to the last 5.4 version (which is 5.4.2.2), first, then you upgrade to the latest version. My preference is Method 2 from this guide:
