Ability to run build and package steps separately
It would be good to be able to just run the build phase of sql CI, without running the package step, and then run the package step subsequently.
Granted, the reason that this would be useful is so that we can modify the scripts used to build the CI database (via a custom script that does variable replacements based on OctopusDeploy project variables), but then we want to revert to the original files to package.
So, potentially, http://redgate.uservoice.com/forums/263916-sql-ci/suggestions/7647198-as-an-deployment-engineer-i-d-like-to-run-environm is a fix for this.
Another way of solving this (that would be more work) is to integrate better with OctopusDeploy for variables, but that might tie you too closely.
DLMA v2 now features powershell cmdlets that are more modular than the previous SQLCI.exe and separate verification, testing, and packaging.
