Moving PDM from Windows Server 2008 to 2012

Our IT/Networking team tells me to prepare for moving PDM Pro 2016 SP4 to a Windows Server 2012 box. And they are recommending I involve our VAR to assist in that transition. Has anyone moved to a new (VM) server? Does it really require the reseller? It seems as though each time I go to our VAR for support, they stick their open palm out. And we are on maintenance. I'm thinking of involving Solidworks Corp. since we have a corporate account with Solidworks. Our IT also mentioned it may be a good idea to upgrade to 2017 Products too. I think my head's going to explode. Is that a good/bad idea - simultaneously moving to a new server AND upgrading products? Wow...Any thoughts/suggestions from experience are appreciated.
