Migrate from centos 7 to ubuntu

chandler1408

Hi everyone, I'm trying to migrate an osticket from a centos 7 server, in eol, to an ubuntu LTS.
The current version of osticket:

osTicket version v1.14.7 (4842f6f)
— v1.14.8 is available
Web Server Software Apache/2.4.6 (CentOS) OpenSSL/1.0.2k-fips PHP/5.6.40 mod_apreq2-20101207/2.8.1 mod_perl/2.0.11 Perl/v5.16.3
MySQL version 5.5.68
PHP version 5.6.40

In the new server I installed php 8.1 and I wanted to install osticket 1.18.1.
I installed mariaDB as in the previous one, I recreated the same users and restored my database. So far, nothing strange.
On the new server I configure Apache, put the osticket directory and, inside the include, copy ost-config.php.
I run upgrade.php, white screen, I try to run setup.php, it tells me that a version of osticket already exists and that I should go to the control panel to update it. I click, white screen.

I take the default ost-configsample, configure it, rename it and run setup again. It asks me for all the information (DB, user and more). The configuration is unsuccessful. Where am I missing?
Thank you.

You need to check your PHP error logs to find any relevant errors. All you need to do is install the prerequisites on the new server (don’t forget all the needed PHP extensions), import your db from backup on the new server, place the new code on the new server, copy over your config file, update any info if needed, visit the login page, login, and run the upgrader.

If you have any plugins installed make sure you download the new builds and place them in the plugin folder before running the upgrader.

Cheers.

If I could suggest an alternative in migration. We too migrated away from CentOS 7, and in the end, after lots of analysis, we chose Oracle Linux. It's based on Red Hat, same as CentOS, so little tweaking is needed. Also, it's free unless you want to buy support and I believe they have a migration tool. Lastly, Oracle issues patches quickly, faster than CentOS. For PHP, though, we have found Remi as better than getting it through Oracle.
