How to upgrade from Magento 1.9.4.5 to OpenMage today

[kamzata]

I upgrade my Magento installation from 1.9.4.2 to 1.9.4.5. Now I want to upgrade to OpenMage.

I followed the migration guide without success.

I run:

• git init inside my Magento directory to initialize the repo
• then I run git checkout -b migration
• then git remote -v but it didn't show any origin
• then git remote add upstream https://github.com/OpenMage/magento-lts.git
• then again git remote -v which showed just the upstream repos (fetch and push)
• then I run git fetch upstream which seems to be completed successfully (it listed all new branches and tags)
• then when I run git rebase -X theirs upstream/main it threw an error: fatal: Could not resolve HEAD to a revision

What am I doing wrong?

Little to go on. Tell us more about your current setup. Do you maybe have a composer based setup?

[pquerner]

Hm. composer should have screamed at you.
https://github.com/OpenMage/magento-lts/blob/v19.4.0/composer.json#L6

Its enforced to be running from PHP7 to 7.4 only.

You are right. I required ^19.4.0 (composer require "openmage/magento-lts":"^19.4.0") and it should have installed 19.4.23 which supports PHP < 8.2.

Maybe instead of directly going from the 19.4.23 to the 20.12.0, should I try to upgrade to something like 20.6.0 and then upgrade to the latest?

Well... I am beginning to repeat myself.
Yes. :D You should upgrade step by step. Check the release notes of each release. I know its tedious. But its the best way, to not end up with a broken shop.

Upgraded to OpenMage 20.0.20 but the problem persists. I didn't find anything worth of mention in the release notes.

Upgrading to the latest OpenMage version is not complicated, if you know what to do.

The database can be exported as a dump, but the problem occurs in the file system. When I upgraded a store that I haven't worked on in a while, I compared the 1.9.2.4 version provided by Magento with the installed one. I deleted everything that was common from the installed version. I checked for any other custom changes in the core files. If the core files were modified in another directory (local, community), then I analyzed the changes with the current OpenMage files. As far as I'm concerned, there were a few more changes that needed to be maintained. After this cleanup I got a skeleton from which to start any OpenMage version. I recommend a test environment, DDEV is a fantastic tool and I created a tutorial to take the benefits. You can find it here #3839.

In the test environment I imported the database, copied the skeleton file system, the OpenMage files from the latest version and started installing the dependencies with Composer. The story is here #4082. The problems that appeared were in the theme and extensions, but solvable due to error messages. In the Discussions section other people asked how to upgrade and received similar answers.

It is not mandatory to upgrade from version to version, but jump directly to the latest version. I would forget about OMv19 because it has not been updated for some time and will enter EOL soon.

That sounds good but with level debug I'd expect some info. What kind of debug is it?

[empiricompany]

if you still can't see the logs, try to force developer mode in index.php

Mage::setIsDeveloperMode(true);

if you still can't see the logs, try to force developer mode in index.php

Mage::setIsDeveloperMode(true);

There's still no output in my system.log file. Do you have some output there?

However, if I try to log something like this Mage::log("My test log.....", null, 'var/logs/system.log', true); it works.

[addison74]

We started the discussion from the upgrade and we came to how to write the errors in the files. The fact that nothing is written in the system.log file means that there are no errors in the source code, where the method is invoked. The troubleshooting must go further with other investigations.

My opinion is to call on a person who can do your upgrade both on the OpenMage side then on other parts such as the theme, extensions, custom code, etc.

[kamzata]

As you were able to read before, all works fine. My only doubt was the empty log since I remembered (as you say, probably wrong) some output on debug level. Thank you.

May be this can help.
