[cisco-voip] Migration strategy

[Ryan Huff]

Any elements that you are going to pre-stage that are a part of the dial plan (translations, route patterns, DNs, transformations ...etc) wilk all need to be isolated from your currently migrated phones.

So the DNs on your device profiles would likely need to be in an isolated partition, but the device profile itself probably doesn't need to be in an  isolated device pool.

If you do this, remember to use a CLLI or some unique descriptor in the description field of all your pre-staged elements, it will make it very easy for BAT to find things later on.

Thanks,

Ryan
