Upgrade tiki from control panel stuck on version 19.0

posts: 4 United Kingdom

I have used the tiki installer (I use the install upgrade not replace database) to try to upgrade from 19.0 to 20.
when you get the welcome page for the installer it says welcome to the tiki 19.0 installer
you then get the install & upgrade page, I choose upgrade automatically upgrade your existing database to version 19.0
you don't seem to get offered version 20 in the upgrade process
it loads and runs okay but when you check the control panel / general it still shows up as version 19 and offers 20 again. Is there a way to force or direct the installer to the next version.
I am running tikiwiki in a bitnami stack on AWS ec2 server.
Thanks in advance

I have an existing site on AWS running 19.0 I am just trying to upgrade to 20.0 through the control panel, I don't want to run a fresh install.

There are many ways to run a Tiki on AWS.

If you use a stack or a script to install you are dependent of this this stack or script.
Still you could (I would do it that way) create a second instance (if needed resize temporary) install a new Tiki (the version you want) and reuse the database (duplicating is safer). You will then have to copy themes and files. Once all clear delete the previous instance.

I installed a few Tiki on AWS and as I needed to be able to control anything I installed a LAMP package with Webadmin and then...

Good luck

Just to clarify I am using the tiki installer option from the control panel
Tiki Installer Start
but when you start the installer it only offers version 19.0
Tiki Installer Welcome
is there a way to edit a file to point the installer to version 20 I have ftp access and can use putty for shell access
thanks Robin

Hi Robin and welcome to the Tiki community!

What you ask for makes total sense and there have been suggestions over the last years to have Tiki support this upgrade process, which is far more user friendly. But no developer has added that feature yet.

Therefore, the only ways to ugprade involve placing in your server the new version of Tiki (20.x in this case) in parallel to the old one (19.x in this case; avoid copying the new over the old one), and point the installer in 20.x to use the same db (or cloned db, in any case, after the usual backup of the db), and upgrade from there.

Documentation about upgrades is here:

If you can get a developer to code whatever is missing to have the other type of easy-upgrade you talk about, many users (and admins) will wave at you! :-)

So the best solution seems to be, you need to learn to use putty for shell access and command line syntax to install the new version and then copy files over. (or get an expert to do it for you)
I found phpmyadmin was okay but hit problems backing up and installing as the file gallery size was too big for phpmyadmin, you need to use shell access.
thanks for your help and guidance.
