Hi @Shreek,
It is indeed quite a general question. If you need support on a general question, I would rather recommend you to get advise from SAS Consulting services and/or your SAS account manager/representative. I am sure they can give you great support and pin-point you to the right direction.
But if you already went through the general questions for any migration (the new installation, security/communications, data, scripts/programs, maintenance, costs, etc), and you got specific questions, as @SASKiwi correctly indicates, please do not hesitate to share them with us.
Thank you in advance,
Regards,
Juan
