Options to purge all the transaction and setup data from a environment

Summary:

For our client currently we have 2 environments. One is Dev and another one is test. For SIT we have loaded the work structure and worker data(via HDL load) into Test environment. And the same data is copied to Dev environment as a T2T refresh.

We want to know how to purse all the transaction and work structure data from a environment since we need to use a same environment for the UAT. For UAT we need to purse all the data and need to reload the fresh data.

Please let us know the options to purse all the transaction and work structure data from a environment.
