Change directory, where server stores mail

I am trying to move the mail store (Yosemite Server). I did a

serveradmin fullstatus mail

and among the many lines of output there is

mail:imap:partition-default = "/Library/Server/Mail/Data/mail"

Will it be sufficient to simply change this parameter by entering

serveradmin settings mail:imap:partition-default = "my directory here"

and then to restart the sever?
