You only need stuff from ENVARC. In your case I would only copy MUI master settings file and not copy any other system setting files. They are old, lot of things changed from 1.4 to 2.0. For example you dont need 3rd party TCP/IP stack anymore.

Also, you cant copy system stuff directly from SYS (by excluding MOSSYS path) because scripts in S can be outdated. I would just use clean install and manually copy required files from old 1.4 install.

If you copied stuff directly from old SYS: you would overwrite some newer stuff in Utilitites, Tools and Prefs dirs. You would also get mix of outdated and new versions of programs, for example PegasosMixer was replaced by Mixer application.

When you have got MorphOS 3.7 running it will be easier as incremental update is supported.
