Hi,
as such there is no DOC but I can share my views:
Under Pros:
a. PCD is an application use to migrate older versions[6.1.5, 7.x , 8.x] running on MCS to VM servers.
b.It can be used to change the IP address or hostname on new servers without affecting existing version .
c. Many users using MCS Hardware are not willing to migrate to latest version because of existing HW not supporting interim releases which they have to hop through to get on to the target release.
d. Further, this requires license re-hosting as well for interim releases and major downtimes as well which can be avoided by using PCD without disturbing existing setup.
e. Also, DRAM/HDD sizing needs to be considered while doing migration on MCS.PCD addresses these issues for migration.
Under CONS:
a. It needs to be ordered through Product Upgrade Tool and bootable is not downloadable from Cisco site.
b. You could face some issues while doing migration which could be bugs but can be resolved.
c.could face issues while discovering cluster/doing migration but can be resolved.
regds,
aman
