Upgrading Tomcat

You will only need to perform this step when instructed to by Krestfield support. If unsure, contact us here: support@krestfield.com

Steps

Step 1

Download the upgrade script from here, unzip and copy the .ps1 file to the following folder: .\certdog\install

E.g.

c:\certdog\install\upgrade-tomcat.ps1

Step 2

Open a PowerShell window as Administrator, navigate to .\certdog\install and run:

.\upgrade-tomcat.ps1

The latest Tomcat version will be downloaded and installed:

PS C:\WINDOWS\system32> cd C:\certdog\install\                                                                                                                                     PS C:\certdog\install> .\upgrade-tomcat.ps1                                                                                                                                         Stopping Certdog service...

Tomcat upgrade complete.
A backup of the previous Tomcat installation is located at: C:\certdog\install\..\tomcat.bak.20260421-1252

Note that the previous Tomcat version is backed up to a timestamped folder mentioned in the output.

Rollback

If any errors do occur then the upgrade may be rolled back. To do this, stop the certdog service. Delete the .\certdog\tomcat folder. Note the backup location that was output from the script e.g.

C:\certdog\install\..\tomcat.bak.20260421-1252

Note that in this example, this relates to: C:\certdog\tomcat.bak.20260421-1252

Rename to .\certdog\tomcat e.g.

C:\certdog\tomcat.bak.20260421-1252 --> C:\certdog\tomcat

Start the certdog service.

Cleanup

When satisfied that the installation is all working correctly you may delete the backup of the old Tomcat files.

Locate the backup location e.g.

C:\certdog\tomcat.bak.20260421-1252

and delete
