Hello Community,
I need your kind help!
We have a customer who has a Nexus 7000 (C7010) and he wants to upgrade the DRAM on the SUPs from 4GB to 8GB, then upgrade the N7K-C7010-FAB-1 modules to N7K-C7010-FAB-2 modules, and finally insert a new N7K-F248XT-25E module.

I've been studying a lot this activity and I found in the documents that 8GB RAM will NOT work unless you have 5.1(1) or later (current image is 4.2(6)). So I'm thinking of doing this activity using multipath ISSU as follows:
| 1 | Upload both 5.2(7) and 6.2(8a) images on the flash of both supervisor engines |
| | |
| 2 | |
| 2.1 | Install the image 5.2(7) on both supervisor engines |
| 2.2 | After switch comes up verify that everything came up successfully |
| | |
| 3 | power off the switch |
| | |
| 4 | |
| 4.1 | remove both supervisors |
| 4.2 | upgrade DRAM on both supervisors |
| 4.3 | Install both supervisors and verify that everything came up successfully and new DRAM is recognized |
| | |
| 5 | |
| 5.1 | Install the image 6.2(8a) on both supervisor engines |
| 5.2 | After switch comes up verify that everything came up successfully |
| | |
| 6 | |
| 6.1 | power off the switch |
| 6.2 | upgrade the fabric modules |
| 6.3 | insert the 10gig module |
| | |
| 7 | power on the switch and make sure everything is working fine |
Does this sound like a good plan ? Has anybody tried such a move before and maybe you can share your experience with me?
Also, there is some information in the 6.2 release notes that don't add up:
http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/6_x/nx-os/release/notes/62_nx-os_release_note.html#pgfId-811971
Table 6 says that you can perform an ISSU from 5.2(7) to 6.2(8a).
Table 8 says that a multipath ISSU can be performed from 5.2(7) to 6.2(6b) but when I look at table 6 I cannot see that ISSU is supported from 5.2(7) to 6.2(6b) so which information is correct? I'm confused here!
Thanks a lot for the help guys !!
