I have an older version of invoice plane and need to move it to a new domain for testing.
Then I want to rename the test domain back to the old domain name to go live when i am happy with everything. I am also moving, converting an old joomla site to wordpress at the same time in the same way. Invoice plane is in a folder of this install like mydomain.com/invoices
First I wondered where i can find out what my version of invoice plane. It does not seem to say in the back office.
Then I wanted to know the steps to update an older version of invoice plane to the latest. Do i have to step upgrade versions or can i go straight from the quite old version (about 5 years or more) to the latest. 1.6
Also when i change back the domain what files in invoice plane will i have to change when i the url of the new install from mytestdomain .com/invoices to mydomain .com/invoices
Any assistance would be greatly appreciated.
I am a self taught web person so i apologise if i am using the incorrect terms here,
