Hi Partha,

There is no "Direct" path from CUCM 6.1(2) to 8.5(1)

		Direct upgrade using DMA: none
Note Refer to the Notes about Engineering Specials (ESs), Service Updates (SUs), and Windows Service Release (SR) Upgrades concerning upgrades from ESs.

So, you would need to move to 6.1(4) as a first step. You will also want to look into

whether or not your current servers are supported in 8.5(1). Here is the master list for

server support;

Rob,

Is this upgrade path supported for Business Edition on MCS7826H3 as well..?

My path needs to go from CUCMBE 6.1(2) to final deployment of CBE6K on UCS C220 (VMware 5)

I realize I have to make at least one jump. would it be best to go from 6.1(2) to 6.1(4), and then to 9.1(1). I heard somewhere it may be better to jump from 6.1(2) to 8.5(1), and then to 9.1(1).

Also will I need to perform DRS/DMA between every path upgrade,.?

This will have to support embedded Unity Connection migration as well.

Please advise...Thanks,

Doug Smith
