Hi - I am trying to upgrade iRedAdmin-0.9.1 to the following, but get the error:

root@website:/root/iRedAdmin-0.9.2/tools# bash upgrade_iredadmin.sh
<<< ERROR >>> No mlmmjadmin installation found (/opt/mlmmjadmin).
<<< ERROR >>> Please follow iRedMail upgrade tutorials to the latest
<<< ERROR >>> stable release first, then come back to upgrade iRedAdmin-Pro.
<<< ERROR >>> mlmmj and mlmmjadmin was first introduced in iRedMail-0.9.8.
<<< ERROR >>> https://docs.iredmail.org/iredmail.releases.html

Do I need to install mlmmjadmin?
