There is an option for cross hypervisors VM creation in instant recovery, what would be the performance (any impact on the performance?), compatibility issues, and what would be the required tools (if any)?
Question
Cross hypervisors VM conversion
+21There should be no performance impact as long as you install the VM tools that pertain to the environment you are moving to. Also test once restored to ensure things work as expected before going live.

Many thanks for the prompt response and advice. I will surely test a VM doing so.

That is key. Many have had no issues while others have had some issues but testing before final move is the best thing. Hope your restores go well.

Please note that during instant recovery, I/O is managed by the backup repository and not by production storage. (Datastore vmware exemple)
Latency is higher and throughput is reduced compared to running virtual machines on production datastores.
In addition, read operations are handled by compressed and deduplicated backup files: write operations are redirected to the redo log or a specially designated cache datastore.
The conversion between hypervisor (disk format, hardware abstraction) occurs during boot.
This adds CPU and I/O overhead on the VBR and proxies during restore.
I do not recommend using this approach if there are critical 24/7 applications.
