Migrate old installation ( to new server with PHP 7.3


I want to move my old installation to a new server.
What is the best way to do this?

I tried to install a clean new Version but this shows only a white screen when entering the site.

When I install I can reach the installer and end with the new version.
But when I import my database backup I end also with a white screen...

What can I do to successfully migrate to the new server?

compress your existing site and download. download your database. install both on your new server. change your config > site.php settings to match your new server. run on php 5.6 then upgrade your install in the dashboard of c5. Once you are on version 5.6.4 you can change php to 7.3

Hello tallacman,

thank you for your help!

I will try this now... (Using old debian 6...)

I successfully migrated the old version to Debian Buster (with additional PHP 5.6).

I will stay with the old concrete5 version because I dont think the "lazydays" theme works with newer versions of concrete5.

Updating from a core you are likely to run into minor addon/theme issues at 5.5 and 5.6. Mainly in edit and dashboard dialogs, where 5.5 introduced bootstrap. So the viability of getting to depends on how much application code and addon/theme packages you have and the upgrade path for such.

If you are the only editor and can accept a few messy dialogs in addon edit and dashboard pages, then you can likely get away with an old theme that doesn't update to c5.6, or at worst only have to make very minor changes to keep the front end of your site looking good.

When moving a database, its best to turn off pretty URLs and all caches before making the SQL backup.

On the way to your new server, I suggest installing a localhost clone of the site and exploring/resolving upgrade possibilities. You can scrub and retry as many times as you like, then when everything is sorted copy that to the new server.
