I'm about to performs a pre-migration of Netware 6.5.

During the pre-migration installation I choose not to install licence. I
do not belive it will be a problem when I will migrate the NDS, but I am
not 100% sure.
Is it safe to do like it?

I could not find a recovery plan in case the migration fails. Do you have
any TID or documentation that describes the way to recovery the source

Tanks !
