I have some SSG5, 20 & 140 firewalls to upgrade, all are currently running 6.2.0r5.0 & i am looking to go to version 6.3.0r21.0.
To my knowledge, none of the existing firewalls currently have a boot loader (looking at the output from ("get sys").
1. So, should i install the relevant version boot loader as part of the upgrade?
2. I have downloaded a document with the upgrade process & it looks straight forward, is there any thing else i need to consider as part of the upgrade i.e. licensing/certificates or any other known gotcha's?
thanks
Colin
