My Company is in discussion of deploying an early version of CUCM 8.x from 6.x. We are currently using the 7835 I2 platform which is supported on the 8.x platform; however, the product will be end of support in May 2014. Is anyone aware of 8.x issues due to 7835 platform? I know that UCS is the preferred platform; however, we may want to leverage our hardware until the end of support. Any information that you can provide will be helpful.
