i am planning to upgrade cisco 6509 non E chasis IOS which is in VSS from SXIV to SXI11.I have the procedure document to upgrade.
my doubt,is it necessary to remove the VSL link while upgrading the IOS.
If i dont remove the VSL link and upgrade the one chassis IOS what will happen.
Existing IOS: s72033-adventerprisek9_wan-mz.122-33.SXI5.bin
New IOS: s72033-adventerprisek9_wan-mz.122-33.SXI11.bin
Waiting for reply.
