[Koha] Downgrade to 19 from 20

[Indranil Das Gupta]

No such Downgrading HOWTO exists AFAIK.

The standard technique would be as follows:

1) Keep a copy of 19.XX database handy. And note down your Koha instance
name with sudo koha-list.

NB if you have more than one instance, pls ensure you note down the correct
instance name.

2) Format your system and install Koha after setting apt to point either at
oldstable (for 19.11) or oldoldstable (for 19.05) .

3) Run koha-create --create-db <instancename> where instancename is your
old koha instance name from step #1

4) import the old database into the newly created instance.

5) either run the koha-upgrade-schema script from the terminal OR let the
Koha web installer do is magic.

If you have successfully completed steps 1 to 5 above, you will be back
with your old version of 19.XX.


Hope this helps
