N5K options to upgrade from 5.1(3)NX(Y) or 5.2(1)NX(Y) to 7.1(4)N1(1)

[andy!doesnt!like!uucp]

Hi NXOS Gurus.
I'm planning upgrade to 7.1(4)N1(1) of the series of N5K switches running quite old images like mentioned in the tytle.
reading the release notes to target version (https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5500/sw/upgrade/714_N1_1/n5500_upgrade_downgrade_714_n1_1.html#69768) one can find Supported upgrade/downgrade paths section stating in the Table 2 Supported Upgrade and Downgrade Paths for Cisco NX-OS Release 7.1(4)N1(1) that minimum Current Cisco NX-OS Release must be in range 7.0(4)N1(1)—7.0(8)N1(1) in conjunction with Note: Note If you want to upgrade from a release, that is not listed in the “Current Cisco NX-OS Release” column in Table 2 under the “Supported Upgrade and Downgrade Paths for a Cisco NX-OS Release” section to the latest Cisco NX-OS release version, then you must first upgrade to a release that is listed in the “Current Cisco NX-OS Release” column and then to the latest release version.

Sounds like another one interim upgrade step, right?

But by reading the document further one can find section Upgrading from Cisco NX-OS Release 5.1(3)N2(1c) and Earlier Releases (Disruptive Upgrade) promissing the direct upgrade from the versions mentioned in this discussion tytle is quite possible but disruptive :)
Could somebody confirm last statement is correct?

Yes. 

5.1(3)N2(1) >> 5.2(1)N1(9a) >> 7.0(8)N1(1) >>  7.1(4)N1(1)



Please refer to tables 5 and 5 & 6 in the following links respectively:

Hi man,

thanks for the response. In case of 5.1(3)N1(1a) (which is exact version in my case :) i was going to jump to 5.2(1)N1(7) somehow... because i've already figured out the path from latter... & it looks like 5.2(1)N1(7)>7.0(4)N1(1)>7.1(4)N1(1) beacuse according to https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5500/sw/upgrade/714_N1_1/n5500_upgrade_downgrade_714_n1_1.html#Supported%20Upgrade%20and%20Downgrade%20Paths%20for%20Cisco%20NX-OS%20Release%207.3(1)N1(1) Upgrade to NX-OS Release 7.1(4)N1(1) is possible from anything in range 7.0(4)N1(1)—7.0(8)N1(1). I selected oldes one :)

then according to https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5500/sw/upgrade/704_N1_1/n5500_upgrade_downgrade_704_n1_1.html#pgfId-769343 Upgrade to NX-OS Release 7.0(4)N1(1) is possible from 5.2(1)N1(7).
Anyway you have resolved the puzzle with 5.1(3)N1(1a) for me , so many thanks to u :)
