I've recently upgraded from Liferay 6.2 to Liferay 7.2, and am in the process of converting the automation processes for deployment.

I've looked through and read this article:
https://help.liferay.com/hc/en-us/articles/360029134911-Managing-and-Configuring-Apps#managing-apps-in-production

With my manual deploys while in development, I haven't run into too many issues just doing hot deploys by dropping the war file into the deploy folder. Of course, stopping and starting the server is going to be more fool-proof, but for a production environment that may have dozens of portlets to start up, this could result in a large amount of downtime.

What is the best strategy for production deployment of portlets that have not been specifically designed to be auto deployable? Are there any clean up tasks I should be adding to my automation?

Thanks!
