Standalone SS with NRS

[ktse1210]

Hi guys,
This is sorta a a continuation from another thread that I created.

I am just wondering whether I am on the right track.

I have Site A, C, D, E, F on Rel 4.5 systems while Site B is on Rel 6.0 system.

Site A is the main site where the IP phones in the branch office redirects to.

I am planning to install (as advised by pros in this forum)
a single card-standalone SS with only NRS (Primary NRS Rel 6.0) at Site A and making the Site B's Leader SS (Rel 6.0) the Alternate NRS.

Then I will make the respective Leader SS of each site, Site A, C, D, E and F the Failsafe NRSs connected to the single standalone Rel 6.0 NRS in Site A.

Is the above feasible??

Fail safe will not work as all need to be the same release.
