I am having trouble understanding IBM procedures

Question

I am reading this file "readme_5202_P8CPE_IF001.htm" (Content Platform Engine 5.2.0.2 Interim Fix 1), and I encountered this procedure:

Copy the new Engine-xx.ear file into the following directory. This directory is a staging location. Do not delete or overwrite the currently deployed Engine-xx.ear file.

Windows
installation_location\ContentEngine\lib

UNIX
installation_location/ContentEngine/lib

What I don't understand is, how am I supposed to copy the Engine-xx.ear file to the specified directory without deleting or overwriting the existing Engine-xx.ear file there? Please bear with me if my understanding in English is not good.

Thank you very much!

Answer 1

That's a note (poorly explained, though) not to overwrite the original file (Engine-xx.ear), but to rename it, as e.g. Engine-xx-orig.ear, and store it aside (to have it if something goes bad with your upgrade) before copying/building the version from a fix pack to that same location.

Which is called a staging environment.

Because it's used to build a WAR/EAR for deployment.

Answer 2

Judging from the rest of the document, I belive that they are trying to tell you that you should follow their instructions carefully, and not try to be clever and overwrite the deployed application (at some other location).

I would give it a shot and overwrite whatever is in installation_location\ContentEngine\lib, the staging location. Make a backup of the files you overwrite in case it doesn't work out.
