Normally a pre-prod system would be used for final UAT (User Acceptance Testing) before prod deployment.

It could also be a system where you always have the same code than in prod, and can anytime overwrite the database with a fresh copy from prod. This would allow you to debug prod issues quickly.

But, it really depends so there's no one answer for this question. You can use it for whatever you agree in your team and with your customer.

Its purpose is to provide an environment that simulates your actual production environment as closely as possible so you can test your application in conjunction with other applications. It really depends if you want to make UAT as you preprod or separate sandbox as preprod.. If you don't want to spend extra cost you can make UAT as preprod.

However I usually prefer to have another stage environment which is exact replica of prod, it changes only during your releases where you will apply deployable package and do your regression. The advantage is using septate environment as preprod is,in UAT you can keep all your code/ Azure Dec ops stories which are approved by your functionals for user testing and merge user approved stories/code to branch which points to preprod environment and create deployable package for final.deployment

Hello Yuji,

I was onced involved in a project where the customer used the pre-prod environment one month before go live to post transactions in parallel - in their old system and in the pre-prod system - because they were afraid that the data would be different :-) After this one month of 'testing' the finally went live with a good confidence that D365Fo is doing what they expected.

Best regards,

Ludwig

Anything before GO LIVE, any data or code which needs to be in production should be validated/tested and hence the need for pre-prod environment.

Directly taking data or code to prod without pre-prod is like carrying a lot of risk and unknowns
