Can earlier CUs be deleted from exchange 2013

I have a server running exchange 3012 CU 12.  Once CU 14 is installed on the server, can the CU 12 directory and files be deleted?

When you install a CU it goes directly to the system binaries. It sounds like that you mean the installation files that are decompressed after they are downloaded. You can delete these old installation files without any issue. They are not required by Exchange.

If you are not sure that these ones were your uncompressed installation files, move them somewhere else (external computer or drive) and delete them after some days. But again, if they are just the files used to install/upgrade the exchange (including the setup.exe and these things) you can delete them without any issue. :)
