upgrade from vCenter 5.0u1 + SRM 5.0.2 to vCenter 5.1b + SRM 5.1.0.1 really not possible ?

Hello,

I have vSphere Enterpsise Plus with vCenter 5.0u1 and SRM 5.0.2 on two sites (SRM for two protected volumes and two recovery volumes on NetApp filer at each site) and I guess its time to move to 5.1 branch. But in documentation to the SRM there is explicitly stated that upgrade SRM from 5.0.2 to 5.1 is not possible. Is it really true ? Does it mean I need

- to be stuck at 5.0 versions forever ?

- to uninstall SRM completely, delete its database, install 5.1.0.1 and create SRM 5.1 and configure it from scratch on each site ?

Or should I just wait for the next release of SRM 5.1 (5.1.0.2 ?) - if so, when it will be released ?

Thanks,

David
