3.10.1 to 4.0.2 for site started in 1.7

Post by rgtr » Sun Sep 05, 2021 2:54 pm

Hi

I have successfully converted two of my eight sites up to J4.0.2

Started on the third one. It converted with no problems. Then I decided to introduce a new layout changing from Category Lists to Category Blogs. I had some problems with menu's ... anyway it turned out to be an old problem - see here: viewtopic.php?f=710&t=988216 and here viewtopic.php?t=672782.

So now I had the 3.10 site as I wanted it.
So then I converted this and disaster. Error: JInstaller: :Install: Error SQL Duplicate entry '1' for key 'PRIMARY'
The backend menu was partly ok. System was knackered. See attached jpg's.
The site gave a Whoopee. 500 Unknown column 'fp.featured_up' in 'field list'

Changed the debug to True ['1'] in configuration.php as suggested - see the attached pdf's.

Back to the upgradeable 3.10.1 version, upgraded to 4.0.2 fine and then made the list to blog changes. All works fine.

I guess there is a typo somewhere somewhere......

Anyone want the backups [.jpa] just ask.

Hi

Thanks for the link. I had already read that. But the things I have needed to do are considerably more.
I have in effect extended the article for my own benefit as I have a few more sites to convert - waiting on Regular Labs for Sliders, Tabs, and ArticlesAnywhere - which started in in J1x or J2x.

NB: this page has no menu etc to make it better for printing - click the title to go back - and yes there is no underline which has been removed.

Meanwhile the last two upgrades to 3.10.2 and 4.0.3 have improved things enormously ...

Enjoy a fabulous CMS

Richard

When I work with merge task for our customer on this month, we have some issues, special it's issue come from database from Joomla, or error direct from Joomla source code, I recommend you:
1/ Go to Admin > Extension > Database, click "Fix" to database if you see any warning/error with database.
2/ If you still can't solve issue with (1), you just go to Admin > Component > Joomla Update, and make update again by reinstall package. This step will override missed file during your update from Joomla 3.x to Joomla 4.x

Hi
Tried all of that.
However since 3.10.2 and 4.0.3 the problems seem possibly to have gone ...

Hello Richard,
That's nice! Update from 3.x to 4.x is a big task, special with extensions compatible.
