ISSU on 4507R fails from 12.2(50)SG to 12.2(52)SG

[e.hoehn]

The problem is that after the standby SUP comes up again after the reload, it negotiates RPR instead of SSO course of:

%ISSU-3-PEER_IMAGE_INCOMPATIBLE: Peer image (cat4500-IPBASEK9-M), version (12.2(52)SG) on peer uid (2) is incompatible

%C4K_REDUNDANCY-6-MODE: ACTIVE supervisor initializing for rpr mode

I checked the feature navigator for the compatibility matrix but couldn't find any data neither for the 12.2(50)SG, nor for 12.2(52)SG.

Does anyone know if ISSU is compatible between these two versions ?

And: will the feature navigator be updated some day ?

Thanks in advance,

Emanuel

I feel IOS it gets negotiated to RPR mode
