v3 to v4 upgrade notes
Posted: 11 May 2020 03:34
I'm finally ready to get off my ass and replace my v3 system with v4.
Now, I wish I could just upgrade v3, but I have made so many customizations over the years, that I *cough* didn't document, that I have no idea what's going to break and what's going to work.
Instead, what I am going to do is to configure v4 to run in parallel with v3 and only redirect some domains through the v4 system. This way v3 will continue to run (since it works) and I can take the time to setup, customize and work out all the problems with the v4 installation before switching over.
I'll put my notes here for anyone who's interested.
The first thing I need to do is to figure out how to redirect some mail from the v3 machine to bypass the efa processing and instead send it immediately to the v4 machine...
[edit 1] the installation from a brand new vm is simple enough, but the documentation for afterwards is woefully inadequate. For example setting up the geoip - there is no information about this at all, so how would new users even know that they need to do it before they need to do it?. The installation documentation should have at least a list of things that need to be done post installation, even if that documentation is a link to the forums. (link added thanks to Henk)
