From irrshaad :
We are planning to move our SAP servers to a virtual machine (VM). and I have some questions related this,
- what is time required to move the SAP system to Virtual machine?
- whether down time is needed for SAP servers?
- Whether SAP system which is running on windows and SAP system which is running on Linux can be moved?
Answer from Robert :
Linux and Windows will both work on VM, we have two SAP environments one on each. The Hosts wil have to be different though. i.e. you have your Windows VMs on a Windows Host and your Linux VMs on a Linux Host.
If you are simply deattaching and presenting your storage from your current physical server to a VM server then this is relatively quick and avoids the need for a 5 to 10 outage to export and import databses.
Clearly you should run through this in a test system to begin with, get your process and timings confirmed, best approach would be to take a copy of your PRD database into test and rehearse the move - that way you should get exact timings.
