The same instructions apply, only now you have additional sets of
RELEASE_NOTES files to read. Everything from 2.3-2.7.
Do NOT use old main.cf/master.cf files unmodified with new Postfix
releases. The "postfix upgrade-configuration" command upgrades your
main.cf and master.cf files.
Note that 2.2 did not have a "data_directory". So you may need
to move some volatile state files and change their ownership.
See the RELEASE_NOTES.
