Can you do an in place upgrade from 3.7.7.11 on Ubuntu 12.04 LTS to 3.8.0 RC2

[Derek Mitchell]

Hi, Is it possible to perform an in place upgrade from 3.7.7.11 installed on Ubuntu 12.04 LTS to the current 3.8.0 RC2 or does this require a new install? If it requires a new install can you restore database backups from 3.7.7.11 into 3.8.0 RC2? If you can do an in place upgrade what would are the steps to make this go as smoothly as possible. 

Thanks,
Derek

Yes, an upgrade should work. However I recommend going to 14.04 first. As always, do a database backup and be prepared for some downtime.

Tim

Hi Tim, 

I just want to double check here. 

I have a v3.7.7.11 system on Ubuntu 12.04 that I am upgrading to v3.8.0 on Ubuntu 14.04

I wanted to minimise the downtime and since the whole lot is on a VM I have built a brand new Ubuntu14.04 and v3.8.0.

Default install adjacent to the existing one. 

Can I then just replace the database on the new system with the one from the old - or are there db structure changes that need to be applied? 

If so are there scripts I can run that will perform those db updates immediately after replacing the default db with a copy of the old v3.7.7.11 version?

Or will the db updates run on restart?

Hi David

If you run the cron.php file (php /usr/share/grase/www/radmin/cron.php) this will apply any database upgrades that are required.

Please make sure you copy both the radmin and radius database.

Also, your squid logs are stored as squid log files, so they won't be transferred unless you also transfer the squid log files. Not sure if you need those transferred for your use case though.

Regards

Tim
