Migrating VMs from ESXi 5.0.0 Host/datastore to new ESXi 6.5.1Host/datastore

Hello,

I have a current ESXi infrastructure, 2- ESXi 5.0.0 Hosts, with SAN Storage  with the VMs successfully backed up by Veaam to external NAS storage daily.
i have purchased 2 DELL EMC R440 servers with internal, 8 bay, RAID 5 storage running ESXi 6.5.1

I'm looking for opinions on how best to migrate 5 Server 2008R2 VMs to the new Host and storage.
My concern is that ESXi 5.0.0 is now legacy with VCenter being 5.0.0 also.
Veeam is 9.0

I was thinking of doing a manual cold migration, by bringing down the VMs, manually copying them over to the new storage,  "Add to Inventory" and start them up.
I may be overthinking this, should I leverage VEEAM?
*My concern is dealing with VMs from 5.0.0 straight to 6.5.1. Am I being to gun-shy here?

I'd appreciate any scenarios that you can offer.
Appreciate.
Jurgen

Why when you have paid for Veeam!

Why not just power off VMs, Backup with Veeam and Restore!

No issues there, when you are READY, and there is no rush or hurry, at your convieience, Update VMware Tools, and Upgrade Virtual Machine hardware BUT this is only needed if you require new VM features!

As for running ESXi 5.0 VMs on 6.5, no issues, we run ESX 2.5.4 VMs on ESXi 6.5!

Thanks Andrew!
I suppose I am overthinking this. It's my first move to new hardware in 6 years.
"we run ESX 2.5.4 VMs on ESXi 6.5!" That is remarkable and reassuring!
I very much appreciate your input!

No problems

Many methods to move migrate hot or cold....

But if you've already paid for the tools use them!

It's also good DR practice!

And why do not use Veeam Quick migration with limited downtime for VMs. More information you can find here:
