CSS11501 to ACE

[a12288]

we are planning to replace current CSS11501 appliances with ACE blades, and we have around 100 SLB services at present.

Has anyone done such upgrade? leasson learning, best practice? thanks

We did that recently (after so many struggles with SNAT) from css11501 to ACE (6506 MSFC)...

SNAT Issues - Fixed it after cisco suggested to configure SLB, SNAT both under one single policy..

Active/Standby Config Sync issues (maybe it is due to the huge config what we have..around 15000 lines.)

Manageability thru GUI (ANM Server takes forever to modify any changes..

thanks, did you do a sharp cut, or migrated services one by one?
