How to replace HDD in VMWare "server"?

Question

VMware

I am just starting to work with virtualization systems, so I ask for the help of those who know!
The situation is the following. I got a "server" from the former administrator on which the VMWare 5.5.0 hypervisor is installed and 3 guest OSes are running (2008R2x2 and 2003R2 SP2).
The "server" in this case is:
Motherboard: ASRoock z68 Pro3 Gen3 CPU
: i3-2100 3.1 GHz
RAM: 8GB
HDD: 500 Gb Seagate Barracuda
does not inspire confidence. Immediately, my fears were confirmed, performance problems were found during the work of users. In particular, 1C with a file database starts for a very long time when loading ...
The option of buying a normal server was temporarily rejected, they promised from next year ...
Therefore, it was decided to replace this miracle of the screw. And the transfer of virtualization to RAID 1, 2 Western Digital RE 2TB 7200rpm
were purchased for this. But now the question has become how to do it all better. And therein lies my problem.
I have already read mountains of information about replicating a VM to another server, replacing screws and migrating back, but there is no iron for this idea.
Now I'm studying the Veeam Backup & Replication documentation, since there is a trial for 30 days, but it's not entirely clear to me how best to do this.
Would love to hear from people in the know!
Thank you in advance!

Answer 1

Make a raid1 array, mount it in vware, and transfer data to it. Can be transferred using veeam software

Answer 2

Raid is good, only 1s download speed will not fix it, the database weighs 600-700 and even more mb, and all this volume must be transferred over the network when loading. Switching to RDP or sql will help here, if the budget allows)
