Any way to have two diferent versions of JAVA running on the same OS?

OS In question is a How to Clone Windows Server 2012 (R2)

I got a pretty old, pretty specific version of Java running on it, so the accounting website/software works properly

but I really need the latest version of java on there to be able to use "document creating" software

I know I cant just use the latest version, since when i tried it messed up the accounting website/software, and the old Java version does not support the "document creating" software, so im at an impass

Hi there

@ReallyFrustratd

Do you just want to "Clone" a W2K12 server or run multiple version of Java or both !!!..

Two ways to do this -- long way and short way.

Long way - create a minimal Windows Virtual machine and install Macrium free on it. Then attach old HDD containing W2K12 server and new HDD and then run clone disk.

Easy way - boot up any linux Live distro from a USB stick or whatever.

Then as root simply run the following command

dd if=</dev/sourcedisk> of=</dev/target disk> bs=2048M status=progress.

As for java you need to get on to the webmaster of the site to see what you specifically need to run the software.

It is absolutely possible to install side-by-side several JRE/JDK versions. ... You can change that, or the JAVA_HOME variable, or create specific cmd/bat files to launch the applications you desire, each with a different JRE in path.

I've had to do this in the recent past trying to run some older SAP ERP software.
