Downgrading the Software

Should it become necessary to revert to a previous version of dsTest, the following steps should be followed.

1. Log in to the dsTest server

Log in to the dsTest platform as devsol using SSH or a utility such as PuTTY.

2. Copy the package

If the target version was previously installed on your server, it should still be in your Loads directory. Otherwise, change to that directory (e.g. /home/devsol/Loads) and copy the target package to that directory.

3. Log in as root

devsol@demo2:~$ su


4. Downgrade System

Debian Downgrades

Enter the same command that is used to perform an upgrade:

dpkg -i devsol-dsTest_2.9.0_amd64.deb

RPM Downgrades

Enter the following command to downgrade to an earlier dsTest version:

rpm -U --oldpackage devsol-dsTest-2.8.0-1.x86_64.rpm

5. Exit root

demo2:/home/devsol# exit


6. Run the downgraded software

The downgrade process stops dsTest. Launch dsTest to restart the process and you will notice that the new version runs.
