I need to know how to Set UP DTAP(Development,Test,Acceptance,Production) environment in SDL Tridion? I need to know understanding for below point in context of DTAP.
Do we need to have separate server for each environment? and need to have separate license for each Tridion environment server?
On Development server,do developer needs to create the actual content? or actual content is created on Acceptance server by author? if actual content is created by author on acceptance server then how it will be tested and verified by tester.
if one phase of development is completed in DTAP environment,and second phase of development is needs to started,in that case do we needs to all regression testing again which include test cases of phase 1 too. because we are working same phase one developer environment for phase two too.
what would be the best approach too deal with DTAP set up environment.
