Passport 8600 CPU upgrade question

[leobadinger]

Upgrading 4 Passport 8600's from 5.0.1 to 5.1.4 tomorrow. All 4 have dual CPU's but don't run HA CPU. We pulled one CPU from two different switches to test the upgrade procedure. Now those two CPUs have the 5.1.4 code. Can I put those back in the original switch and let it boot to 5.14 or do I have to do the boot p80b5140.img again once it's in the original switch (not where the upgrade was run)? Also, does it matter if I upgrade the primary CPU before or after I put this secondary CPU back in that has the 5.1.4 code on it? Thanks.

Well I was able to just insert the CPU's with the new code without anything extra. It booted to the new version.

just want to mention this. I forget which version, maybe 4 but it might be version 5. But if you reformat flash and install 4 or 5, you'll get 64MB of flash mem.
