Upgrading from an older samba4 installation.
-For users of samba4 alpha 8 and after
-=====================================
-
+* Compile the new version of samba4 by following the HOWTO, but do
+ not install it yet, and do not run provision.
* Stop any samba process
* Backup your samba4 provision:
- go in the directory where your samba4 provision is stored (/usr/local/samba by default)
- do tar cf $HOME/backup.tar private (it's also recommended to save the etc/smb.conf and var/sysvol dir aswell)
-* Go in the source4 dir
-* run ./python/scripting/upgradeprovision
+ go into the directory where your samba4 provision is stored (/usr/local/samba by default)
+ do tar cf $HOME/backup.tar private etc var sysvol
* do make install
+* run 'samba-tool dbcheck'
-For users of samba4 alpha 8 and after
-=====================================
+This will do a consistency check of the data, and is all most existing
+installations will require.
-* Stop any samba/smbd process
-* Backup your samba4 provision:
- go in the directory where your samba4 provision is stored (/usr/local/samba by default)
- do tar cf $HOME/backup.tar private (it's also recommended to save the etc/smb.conf and var/sysvol dir aswell)
-* Go in the source4 dir
-* run ./python/scripting/upgradeprovision --full
-* do make install
+If you are upgrading from a quite old provision (Samba 4.0 alpha 13 or
+earlier) then running upgradeprovision will do an upgrade of security
+descriptors, and upgradeprovision --full will perform a more
+comprehensive upgrade of the data (including schema and display
+specifiers). This attempts to do a new provision, and to then copy
+existing data into that database.
+
+If you are upgrading from a more recent version, particularly alpha16
+or later, then it is better *NOT* to run upgradeprovision as the
+database format has not changed.
+
+To upgrade from BIND9 flat files to the internal database store for
+Bind 9 DLZ, use ./source4/scripting/bin/samba_upgradedns
