In relation to our ongoing deployment setup/troubleshooting on DEV. While waiting the DEV completion, we are planning to advance the activities of SIT and UAT phase by cloning the Fresh Pega 8.8 installed from DEV to SIT and UAT, to follow importing the packages. Currently, we are on premise setup through Virtual Machine each DEV, SIT, and UAT has its owned instance. Requesting a document guide (best practice) how we can clone the Pega 8.8 installed only from DEV to SIT and UAT, we will do later importing the packages?
