I would like to have some advise on what would be the safest and best way to upgrade a 7500 with dual RSP4 cards using HSA.
I want to replace the 2 RSP4 cards with 2 RSP4+ cards instead.
1) Should I turn down the router and swap the 2 cards out by the new RSP4+ cards?
2) Should I swap the standby RSP4 card by the RSP4+, force the switchover to the new RSP4+ and then replace the remaining RSP4 by the RSP4+.
The RSP4+ cards have a larger DRAM than the RSP4 cards.
Thanks for your advise,
If you can have a maintenance window, do .1.
This way you rule out any possibility of fight between cards, and can upgrade IOS as required.
If you cannot stop the router for 30 min, then .2.2 is the only choice. But it's more risky.
Hope this helps, please rate post if it does!
