moving /var/vmail/vmail1 Maildir tree to another partition?

I have a small Postfix/Dovecot/MariaDB on Centos 7 with a dozen virtual domains, I'm running out of space in /var but got space

can I simply move the entire /var/vmail/vmail1 tree elsewhere ? like say /vmail/vmail1

is it as simple as shutting Dovecot/Postfix, move tree, edit conf and re start ? or am I missing something ..? or is the a better way of doing this ?

# grep 'var/vmail' *.conf dovecot.conf: sieve_global_dir = /var/vmail/sieve dovecot.conf: sieve_global_path = /var/vmail/sieve/dovecot.sieve dovecot.conf:# location = maildir:/var/vmail/public/:CONTROL=~/Maildir/public:INDEX=~/Maildir/public

# cd ../postfix # grep 'var/vmail' *.cf main.cf:virtual_mailbox_base = /var/vmail

# dovecot --version 2.3.11.3 (502c39af9)
