We’ve been involved in resuscitating some ExpressionEngine 2 websites lately, and before we can get them to EE6 (unless we start fresh from scratch), we need to get them to EE3. Once we get over that hurdle, getting to 6 will probably be a lot easier.
That said, along the way, we’ve had to do various plugins, add-ons, and extension audits, and I thought it’d be helpful to list some of our findings here to help developers and owners in similar situations.
Let us know in the comments if you’ve had different experiences with the listed ones or if there are any others you think we should test/add.
