I'm sure someone has done this. I deployed the ADS(SAL GW only) 3.0 ova and have it up and running. I do not have many managed elements and was going to move these over from the 2.5 one at a time. Am I able to re-use the same SEID from the old SAL GW? I tried going into grt and choosing SAL GW migration to generate a new SEID and it said that has been decommissioned and sends you to a link on how to move the managed elements. On the new SAL GW GUI there is an option to register it, which then prompts me for my SSO creds. Upon entering those I get a 'Bad Gateway' error page. If I can just re-use the same SEID that would be ideal.
