Expand LUN which is cloned with RM 5.5.2.0

Hello,

I have a space issue with a device (from a VMAX) which is cloned every day using Replication Manager (ver. 5.5.2.0). I need to expand this device (and its clone). What will be the procedure to apply on Replication Manager to reflect the expansion (the new size of the LUN). To expand the device it is an online activity but is that supported by Replication Manager?

Thank you,
