Thank you for all your help guys, it was a success. The upgrade manager told me to go through all the 16 upgrades from 3.6 to 16 and it went well.
Small issue though, the new version has a few errors i was not able to fix, namely:
I get an error on the front page about access to a file that is restricted.
The profile user picture/avatar is huge and does not go away or stay in the top right corner.
The members list is broken.
Any ideas what might cause this?
I have attached images of all 3 problems in this window.
Upgrading from such an ancient Dolibarr version has some challenges but they are manageble if you have the patience to upgrade using all the older versions for migration and NOT to upgrade with only the latest PHP-code. In the historic chain of upgrades some some erros exist.
We have done various migrations (v3.4.2 & up) several times succesfully and might be able to help you.
Just send a SQL-script of the original database and we will give it a try to help you out.
I think the problems are theme related. As you know the “Eldy” theme is the only official supported skin for the application. And after changing some data in the table “llx_const” (without truncating all the data), the application seems to work. But since I only got a SQL backup file, the external modules like the Patas tools and LDAP obviously don’t work.
When you have a look at https://union.dolibar.nl/ this represents the current state of the UI.
As an administrator you should be able to backup the database and restore it in your environment.
Hopefully you can continue working with this Dolibarr instance.
Brilliant it looks better than my version. I don’t see the table data to compare it to mine. Much appreciated. I have a list of upgrades we need to do, this would segway into a paying contract since you were so helpful. Thanks so much Theo.
No problem Nicolas. What you can do is take the table structure from a fresh v16.0.3 installation and generate a SQL backup on https://union.dolibar.nl/ [Admin Tools → Backup] and compare those two files. This should give you the correct information about differences in the data.
Btw: The SQL-backup can be restored on your Dolibarr V16.0.3 and will work correctly.
Unfortunately your version is corrupted like mine. If you look carefully when you navigate to the user icon on the top right you can no longer have the options show up to logoff or see your users options.
