FOS to FOS Compatibility - Validating Connectivity between new and old

How do I validate the compatibility of an old NEC 300 running FOS 5.3 with a 48K running 6.4.3c and an 8510 on 7.1.1? I'm  looking to upgrade the FOS on the 48K and 8510 but I'm concerned it will break the ISL link.

FOS release notes contain information about compatibility between versions.

Hello,

 

Read the release note of the higher FOS version you would like to implement and check the compatibility with older versions.
