Our Data Center comprises of 14 physical servers (many are old) and we are planning to replace them. In order to have optimised plan we  are thinking to buy three physical hosts (each 6C/2P, 128GB and 2x300 GB HDD on each server) and virtualise them (HyperV). Among the 14 we have 3 ERP servers as well which we will replace with Physical server and no plans to virtualise it. All 11 servers are windows based and 3 ERP servers are Linux platforms.
I need to know the following

1) 3 Physical Hosts are enough to virtualise the 11 existing physical servers (I know 3 with the above config is more than enough but we may add more virtual servers in future so have considered that also), Hope this sizing si fine

2) Out of the existing windows servers we need to do P2V along with applications (these applications are mysql based applications). Is there any other factor to be considered for P2V (got the confirmation from applications team that it will support virtual plaforms)

3) Exchange 2016 implementation is one of the main tasks to be done in the virtual servers. Planning to keep two virtual servers with DAG for Exchange 2016 with HA. TTotal mailboxes are 150. Please suggest if any suggestions are there

4) We are going to have separate storage (SAN) with 24TB. Exchange 2016 mailboxes will be on SAN

5) Is there any template to prepare the checklist for the above (basically the proper sizing etc)

6) Backup technology which can be used to take both physical and virtual platforms to be identified - please suggest the most cost-effective (includig file server backup, hyperv machines, exchange 2016  and oracle ERP)

7) A good temlate which can be used for the whole excersie

I am personally not a big fan of virtualization. Even Office 365 doesn't runs on hyper-V. As far as sizing Exchange 2016. You can use 2013 sizing calculator.  Check this:

You can explore DAG option for HA. however keep servers on two different hyper-v servers not on same box. Also don't assign resources to Exchange server dynamically, like RAM or CPU. For other servers, you need to check vendor recommendations related to hyper-v and size them accordingly.

Excel spreadsheet, and add up all the memory, cpu, storage.

Memory is always the bottleneck, very rarely CPU.

or you can use some science behind it, and use Microsoft Assessment and Planning (MAP) Toolkit
