if it's a change that does not incur backwards compatibility (e.g.
adding a tileset, changing the cache backend for a tileset,
enabling/disabling a server, ...) you can just issue a graceful
restart on the webserver. In your case (change of resolution), the
path you suggested is the correct one.
What is the recommended approach to dealing with stored tiles when changes to
mapcache.xml are made, such as a change in the set of resolutions in a grid?
Should we disable the Web server, delete all the existing tiles then restart
the server?
Many thanks,
