I just wanna ask how were you able to create another storage groups/message store in zimbra?
I'm very new to zimbra and we are planning to migrate from exchange to zimbra after using it for almost 3 years.

In exchange, we would open the Exchange System Manager, Go to Administrative Groups -> Right click Servers then New Storage Groups then create another message store inside the New storage group.

I am also new to linux and I think zimbra's administration would be half gui and half command line.

So, how do we go about creating another storage groups/message store in zimbra?
maybe you can point me to a guide or wiki.

Any help would be highly appreciated.
