We have ERP system has operated for nearly 9 years, including:
* 1 ERP01 name server running on Windows Server 2003 Standard 32bit (due to not upgraded ERP, have to use old Windows) – physical
* 1 server named SQL01 SQL Server 2005 running on 64-bit Windows 2008 R2 Standard – physical There’re also 2 Domain Controllers.
We would like to have online systems, ie 1 in 2 server is corrupted, the system should still run or downtime is within 2-3 hours. With the old operating system then I think can use only virtualization. We don’t want to change much on the system. For no downtime, I think no way as the ERP application itself doesn’t support, and old OS, old SQL Server, etc … Can you advise what is solution that we can apply to get the downtime within 2-3 hours ?
