Adding a hot shelves on our existing environment

[KIIKANZAVANNA]

Hi, 

We have our existing environment with *2 v3240 with *4 (*24 disks per shelf each 2.5TB SATA) shelves  . 

The current raid group is 11 and we are planning to add addittional 2 more shelves each with 24 disks with 2.5TB SATA(DS2246). 

1. Is it realistic to hot add on our existing environment? This is a backup filer and we have many snapmirror destination volumes. I am thinking of snapmirror break to stop the replication whilst this adding job is taking place but should it be cold added? Any thoughts?
2. I don't think raid group can be expanded as it will max up and  I think the new aggregate should be created but I think I need an advise on this. 

Pleaes let me know your thoughts. Any more info needed please ask. 

Thanks

Many thanks

Regars
