 === OpenLDAP configuration database ===
+First of all, check if there are important changes in the base configuration of slapd.  For this, we can copy the old configuration into some directory on the new server and run a recursive diff:
+ # Run on old server
+ rsync -r /etc/ldap/slapd.d/ feministwiki.dev:/tmp/slapd.d
+ # Run on new server
+ diff -ru --color=always /tmp/slapd.d /etc/ldap/slapd.d | less -R
+There are going to be a number of changes that are expected.  Namely:
+# CRCs, UIDs, timestamps, and other such auto-generated fields
+# FeministWiki-specific things that only exists in the old configuration
+If these are the '''only''' differences you can see, then it should be safety to completely override the config on the new server with the old one, using the instructions in the following section.
+Otherwise, skip to the section after that and recreate the FeministWiki-specific configuration from scratch.

+''Note: This is an '''alternative''' method to that described in the '''next''' section. See above for which one to choose.''
 Stop the LDAP server and delete the configuration database '''on the new server (careful!)''':
