Recommended migration path from Joomla/VM 3 to Joomla/VM 4

Hello Seyi,

is there a documentation for the recommended upgrade path to Joomla 4?

I deactivated AwoCoupon in Joomla 3 and migrated to Joomla 4. On installing AwoCoupon 4.0.1.0 over the old version I got errors, so I removed the old folders.

I am still getting the error:
Unknown column 'image_config' in 'field list'

Having a migration documentation from the beginning might help to avoid any issues.

Hello,

Your tables are not updated.  Did you do this:

- load the awocoupon dashboard page, which should automatically upgrade the tables

Hi Seyi,

thanks for the help. It works now.

Initially I did the first step only, including deleting all folders, but it did not install.

This time in the test environment

- I deleted the old tables,

- installed version 4.0.1.0

- deleted the tables again.
- updated the live site from an old AwoCoupon 2 to the provided version 3.x.
- exported the awo tables from live.

- imported to the new installation.

This time the migration of the tables worked.
Inbetween I tried to use the old AwoCoupon 2 tables as I found in the live store and got a spinning wheel forever.

So it's important to upgrade the J3 install to your latest 3.x version I guess and then use those tables.

If you pin a documentation like that somewhere, it could help to finish this faster.

Thanks again for your quick help

Hi there,

in my case, after fully deleting Awopcoupon and tables and doing a fresh installation of Awocoupon 4 (4.0.1.1), I receive a "Specified key was too long; max key length is 1000 bytes". The hint suggested on https://awodev.com/forum/thread/item/14310 did not work here, so it seems to be another table causing this issue.

Thanks for helping and documenting.

Niko

Hello,

Get the latest version of AwoCoupon, 4.0.1.2.  With it, the above post should work without any tweaking:

Good morning,

also a fresh installation of AwoCoupon 4.0.12 without any old database tables results in "Specified key was too long; max key length is 1000 bytes". Let me know which logs I can provide for your analysis.

Hello,

You would have to manually install the tables to find out where it is dying.  The table sql can be found in

/administrator/components/com_awocoupon/awocoupon/libarary/linstall/mysql.install.sql

You will need to change #__ to your actual table prefix.  Use phpmyadmin to install one table at a time.

Hi,

the error happens for both #__awocoupon and #__awocoupon_history. The other statements are fine. The first two tables can be imported when I change the column length from 255 to 200 for every relevant column.

After that, the other steps went fine.

Regards,

Niko
