I have a task of upgrading the FOS from V6.2.2b to V7.x. We are maintaining a core-edge topology with 48k and DCX as core switches & around 46+ switches as edge switches which includes(200e,4100,300E,5100,5300). Currentlly 48K is at v6.2.2b and DCX is at v6.4.3b.
As many of you know that 200E,4100 are EOL & EOS, now my question is after upgrading the core switch DCX to 7.x how can i make sure that there will be backward compatibility with 200E & 4100 or 5300 etc..
also, can any one help me regarding the steps that i need to follow for this activity or is there any one who are aware of the issues that i will face after upgrading the activity..
