multiple wordpress installs

Hi @schwende – I saw a few resources that may be helpful for you.

There is some info on moving WordPress: https://ww.wp.xz.cn/support/article/moving-wordpress/

and some other documentation about managing a multi-site network: https://ww.wp.xz.cn/support/article/create-a-network/

Was also able to locate an older thread with documentation about vhost and multisite, that may have some useful info on it too:
https://ww.wp.xz.cn/support/topic/apache-virtual-hosts-file-for-wp-multisite/
https://ww.wp.xz.cn/support/topic/virtualhost-file-for-multisite/

I know some of it might not be specific to Red Hat – looks like they have info in their customer portal — but this might be a good starting point.
