Hi,
i’ve tried to use a VM on ProxMox with openSuse 15.2 and repositories to install PHP5.6 because we need an old web app that works only on this php version.
But I’ve found a lot of problems with this configuration, starting from the binary of php itself, that don’t start returning a core dump at start.
In the short term not – it’s possibly a faster / quicker solution to get the site back up and running than, migrating the application to a newer PHP version …
Time to install an openSUSE server and get it up and running on the net – about 1 hour – maybe 1 day …
Time to migrate an application to a newer PHP version – find a suitable programmer
→ 1 day / 1 week / 1 month / 1 year – plus, 1 day / 1 week / 1 month to perform the migration – plus, 1 day / 1 week to test and verify the changes … Total time needed – between 3 days and more than a year … >:)
