Hi Sheena,
We haven't started archiving yet, but in anticipation of when we do need to, I worked with a CA partner and he helped write up instructions for how to do that (which is basically the same thing as what Jon and Alex said). I'm sharing the instructions below in case it helps.

To retrieve and load a ticket back into the system:
Go to the archive folder on the primary server where data is archived to.
Find the file that contains the ticket number you wish to retrieve by using a tool, such as ‘TextPad’.
Click on Search / Find in Files. For example, search on cr:604846 – Browse to the path where the archive files are, and click ‘Find’.

The search results at the bottom of the screen will show you what files it finds that ticket number in.

Click on the desired file to open it.
The easiest thing to do at this point is to load that entire archive file back into the system. All tickets in the file will be loaded, but
will all archive out again the next time the archive & purge rules run.
The command to issue on the primary server to load the file contents back into the system is:
pdm_load –v –f filename.dat > filename.out 2>&1
This command will load the data in the filename.dat file and write the output of the command to the filename.out file. Recommend file name to be the same as the rule name for consistency.
If you do need to just load one ticket, you’ll need to copy the contents for that ticket from the file into a new file. (txt, dat etc).
Find where that ticket number first starts in the file, and copy from the ‘TABLE Call_Req’ line above it, all the way until the line before the next ‘TABLE Call_Req’ line. Paste that into a new file, save it with a name. Use the above command to load this file’s contents back into the system.
