We are about to embark on the journey to upgrade Maximo 7.6.1.3 to MAS 9.x. I am currently looking for a Technical Specification for MAS, that I can distribute to our Integration Team, and our Analytics team, so they can get some understanding if they need to prepare in any specific way from how things look today to what they need to do for MAS. Is there any such documentation available?
