rsync
should do the job

depending on your whole machine setup it might only be only
umount old /home and mount new(bigger) /home after sync
,perhaps with tmp store elsewhere
( for sure you have to have a plan before doing..)

but your dovecot is very outdated, i would recommend
get up to new hard and software/os install, and then migrate
to new machine
