Can we make changes manually on production end user pages?
Customer Portal, All versions
We do not recommend making changes manually to end-user pages in production, you should always be following the deployment process explained at Answer ID 2849: Deploying Customer Portal pages.
There are number of optimizations done during the normal deployment process such as:
- Making one big CSS file out of all the individual CSS files
So it is not just copying source code files between "Development to Staging to Production", doing these modifications manually can break end-user pages in production.
