today I want to leave a short comment about how to make few Acumatica instances of single developer machine.
As you already know or maybe know, Acumatica recommends to have one version of Acumatica. But what if you want more? Is Acumatica merciful enough to allow you this? The answer on this question is strong yes!
All that you need to do, is to install version that you need, and then preserve following folders in safe place:
And then you can uninstall them and install another version.
starting from 2018 also include devicehub.
Then for installing specific instance of Acumatica you'll need to run AcumaticaConfig.exe file and you'll be ready to go.
