Steps for retrofitting release changes into the templates

If you used an earlier release of PKI Services, you might need to retrofit changes in the pkiserv.tmpl certificate templates file. (You would not want to replace the file if you customized it in the previous release.)

You can use a file comparison tool to compare the new PKI Services certificates template file (/usr/lpp/pkiserv/samples/pkiserv.tmpl) and your existing PKI Services certificates template file (/etc/pkiserv/pkiserv.tmpl).

Perform the following steps to retrofit changes into the pkiserv.tmpl certificate templates file so you do not lose any customization that you made in a previous release.

Make a backup copy of your current certificate templates file. For example, enter from the UNIX command line:
```
cp /etc/pkiserv/pkiserv.tmpl /etc/pkiserv/pkiserv.backup
```
_______________________________________________________________
Copy the new sample templates file to the runtime location. (This is the copy you edit.)
```
cp /usr/lpp/pkiserv/samples/pkiserv.tmpl /etc/pkiserv/pkiserv.tmpl 
```
_______________________________________________________________
Using a compare program of your choice, compare the two template files:
- /etc/pkiserv/pkiserv.tmpl
- /etc/pkiserv/pkiserv.backup
_______________________________________________________________
Edit the runtime copy of the templates file (/etc/pkiserv/pkiserv.tmpl). Using the compare output that is generated in Step 3, merge the changes that you made to the original template file into the runtime copy of the templates file.
_______________________________________________________________
Exit the file to save your changes.
