So we are in the process of finding another MSP(or Outsourced company) as current one have screwed up multiple times. we have inhouse IT as well but there are parts like VM hosting and Connectivity between sites etc are managed by this outsourced company
wondering anyone in the community has experience in terms of what all they had to do and what pitfalls we can avoid
Top of my head i would imagine that we need to have same IP ranges for Networks and Server else we will be in big trouble.
Cutover needs to occur as bing bang with major outage.
any ideas would be greatly appreciated.
