Upgrade from 2.5.28 to 3.5.1 - 1062 - An error has occurred.

[jumanji007]

As the subject says I am trying to update a very old website:

Upgrade from 2.5.28 to 3.5.1

I have followed all the instructions and disabled all non Joomla extensions, plugins etc etc

When I hit the install button I get the following (see below).

I have been reading that when I - install - fail - then restore using Akeeba - then the database becomes a bit out of whack but Im not sure how to fix this issue? I mean not sure how to edit the database/mySQL.

Please help

Did you disable the 'remember me' plugin' ?

Also
The problem with some 2.5/3.x compatible extensions 3rd party extensions is that they use different install files. Even when a 2.5/3.x compatible extension uses the same zip is that some will detect the version of Joomla and install the files accordingly. One way to avoid 3rd party extension files corrupting the update is to update the database and 3rd party extension files separately.

• Update the database with files from a fresh Joomla 2.5.28 install
  Install the 3rd party extensions into a fresh Joomla 3.x.0 install
  Then connect the 3.x. Joomla and 3rd party extension files to the updated database.

You might consider installing wamp on your PC (mamp on a mac) and performing the migration locally. That way you can try an alternative method of migrating.

1. Install a fresh Joomla 2.5.28
2. Create a new database and export/import the data from the database of your live site
3. Edit the configuration.php (of the fresh 2.5.28 install) to use the new data.
4. Go to the Joomla update component and run the update
   This allows you to update the database with fresh Joomla files without files from 3rd party extensions interfering with the process.
5. Install a fresh Joomla 3.x in a separate folder to an empty database
6. Install your 3rd party extensions into the fresh 3.x
   This creates the 3.x Joomla and 3rd party extension files
7. Edit the configuration.php (of the fresh 3.x install) to connect to the updated database (that has your sites data)
   This connects the 3.x Joomla and 3rd party extension files to the updated database (that has your sites data)

----------
Or try
Install the latest Joomla
Install 3rd party extensions
Use https://extensions.joomla.org/extension/j2xml/ to transfer Categories, Articles and users. They have a version for 2.5

Hi,

I managed to get the upgrade to work by switch the template to beez. The problem is I have a gantry template installed and it is very old. Should I be updating this template before updating Joomla or after?

[Webdongle]

I would set Protostar as default then update Joomla then update he gantry Template and reset it to default.
