We are planning to upgrade the RAM from 256 to 512 MB each on our two ASA's 5510 which are in active/standby mode. I was wondering if anyone has done this and how can this be done with minimum or no downtime.
My thoughts were to shut the standby and replace the memory and bring it back up. However at this time the two ASA's will have different memory configs so will the active/failover work?If it works then I can make the standby active by shutting down the primary(active) and then upgrade the memory on that.
Let me know if there are documents anywhere on this or if anyone has successfully done it.
