Path substitute and original flies/dirs

Hello pals, sorry if my question is at wrong place.
I try to make centralized storage of settings for all my 3 boxes and one PC, hope and for addon settings. For that I have up and running Debian with Plex, MySQL, Samba etc. all setup.
My question is, if place substitute paths in Advancedsettings.xml for exmpl:

Code:
<substitute>
    <from>special://profile/playlists/</from>
    <to>smb://192.168.1.110/kodi/userdata/playlists/</to>
</substitute>
<substitute>
    <from>special://skin/</from>
    <to>smb://192.168.1.110/kodi/skin/</to>
</substitute>
<substitute>
    <from>special://profile/sources.xml</from>
    <to>smb://192.168.1.110/kodi/userdata/sources.xml</to>
</substitute>
<substitute>
    <from>special://profile/mediasources.xml</from>
    <to>smb://192.168.1.110/kodi/userdata/mediasources.xml</to>
</substitute>
........same for other dirs......

should I delete original files and dirs?
Or delete all the origins to be sure I’m using only network files ?
Or should I left in place for spare in case of lost central server/network failure ?
Thanks in advance for any answer or guidance on my goal.
