We want to create a solution of our currently working code before we go for new changes in the code.
What is the preferred environment for creating solution in this scenario,
Like in UAT/preprod or in prod? what are the industrial best practices for creating solutions in service center?
Hello.
If all environments have the same version, doing the Solution in one or the other won't make a difference.
My advice is to do it in the environment you are going to recover it so you don't need to take all dependencies along. Just the modules you are going to change. Assuming you are changing the code in DEV, you should do it in DEV.
But, for instance, to create a PREPROD, you should copy from PROD.
And if your factory is a full mess (multiple developer teams working with poor communication), you should copy PROD (the one stable) to DEV and start publishing forward.
