Is there a way to upgrade api versions of all apex classes without manually updating each of them?

I have an org with hundreds of apex classes, all of which have api versions ranging between 30-37. Is there an easy way to bring them all to the latest api version at once without resorting to manual updates?

First of all, I would like to say, do this only if you are certain you have sufficient unit tests to catch anything that might break. Also, make certain you back up your code. I cannot stress this strongly enough.

You can do this pretty easily with any IDE, Salesforce DX, workbench, etc. The general process is either two or three steps.

First, download the files you want to update the API version for. Next, use a tool to "Find and Replace in Files". All major IDEs have this feature. Replace <apiVersion>.+</apiVersion> (a regular expression match) to the desired version. Third, if your IDE doesn't automatically deploy the changes, deploy the changes back to the server.

<apiVersion>.+</apiVersion>

Firstly, do heed sfdxfox's warning. It is very important to backup your metadata before embarking on such a large scale update of the api versions.

Make sure you run all the test cases before and after to look for things breaking. They might break in strange and unexpected ways.

If you can, try this out in a scratch org first so it is easy to experiment and roll back if required.

René Winkelmeyer has created a SFDX plugin that can automate this process for you. It will either target the highest version in the target org or you can specify a target version.
