[cisco-voip] CCM DevPack and SR Interactions

[Matthew Melbourne]

I'm considering an upgrade to CCM 4.1(3)SR6. However, this has not yet
appeared on the compatibility matrix with CRS 4.0(5).

In order to add device support for the 7921s, it is necessary to apply a
DevPack. I was hoping to do this with the application of SR6 which itself
includes DevPack 64. 

If I apply the standalone DevPack 65 (which is compatible with the
existing CCM 4.1(3)SR2, will the later application of SR6 overwrite the
device loads set by DevPack 65?

Obviously, when device loads get updated there is the possibility that a
large number of phones will attempt to update at the same time. What is
the robustness of this procedure (assuming one TFTP server on the
Publisher)? Is it advisable to reload phones in a controlled manner,
perhaps on a site-by-site basis by bouncing switch ports?

Cheers,

Matt
