Have recently upgraded 6500 Wism from ver 126.96.36.199 to 188.8.131.52.
Upgrade process was successful but noticed that secondary image still is in the previous version (184.108.40.206).
I have read that to upgrade it we must use ER Boot release image,
but the latest ER Boot image but latest available is only 220.127.116.11.
Q1. Is it acceptable to leave it as is?
Q2. If not, What ER (Boot) image is recommended ?
Tnx in advance.
