ASR1002x IOS version

[Steve Coady]

Hello

We recently purchased (2) ASR1002x devices as WAN routers for our Data Center(s)

They currently have "asr1002x-universalk9.03.07.04a.S.152-4.S4a.SPA.bin".

I wanted to check for updated version and was a little overwhelmed by the new versions and all the "caveats (resolved and unresolved)

Would someone please provide some expert guidance on this device and what version is considered most stable.

I am currently using 3.12.1S and it's been good.  Previously, I was using 3.11.0S and this was fine too.

If you want to upgrade, make sure you also upgrade the bootstrap.  If you do this right, you'll only need to reboot the appliance once and you've upgraded the bootstrap and the IOS concurrently.

Thank you for the guidance

Wouldn't the bootstrap automatically be upgraded with the IOS?
