Hi there,
I'm still running JEM 2.1.3 on a Joomla 3.7.5 site (Helix III framework template)
Now Joomla 3.8 is out, I want to update JEM first to 2.2.1. (The newest version).
What is the best way to update JEM?
I have used custom.css inside JEM. I won't lose these (I have allready copied these files)
And I won't lose all my data (over 500 events!)
Before updating I will offcourse make a full-backup of my site.
Looking forward to your replie,
Romke (smelnesport.nl)

Hi, update from JEM 2.1 to 2.2 on Joomla 3.7.5 is a normal one click update. Better to save the custom.css specially. And if you have special template overrides for JEM you will have to adapt them.

Hi Romke,

it could be helpful if you take all files you changed, but also their original from JEM 2.1.3 and those from JEM 2.2.1. Then you can make a three-way-diff to create your modifications corresponding to 2.2.1.

Another way could be to make a "dry run" by installing a webserver (e.g. xampp) on a local pc where you can restore your full backup and try to update JEM without risk. (I should like to point out that local webservers like xampp may be configured fully unsecure by default to make developer's life easier so you have to ensure nobody can access your local pc to protect the secrets of your site's users)

Additionally you could export all events, categories, and venues via JEM backend. So on trouble you could import these data. Generally JEM is designed to be able to update from any official JEM release. But it could be possible that the server is too slow and/or the timeout is too fast to handle all the adaptions in time.

I'm very optimistic updating JEM is smart and without trouble - but I can't give a guarantee. ;)
Pessimists are optimists with experience!

Hi Guys,

It took a few days before I had time to update.
Thanks for your replies.
I have succesfully updated Joomla to 3.8.0 and JEM to 2.2.1
JEM updated by just installing it. I had no problems.(For security reasons I had secured all my data and files of JEM as suggested, but no worries)
