INSTALL_DONT_AUTO_UPGRADEオプションを使用した後、完全なアップグレード手順を実行するため、/opt/couchbase/bin/cbupgradeを使用することができます。cbupgradeのコマンドラインオプションは、次のとおりです：

[root@localhost ~]# /opt/couchbase/bin/cbupgrade -h
Usage: cbupgrade [-c path/to/previous/config/dir] [-a AUTO] [-d FILENAME] [-n] [-s FACTOR]
-c <path/to/previous/config/dir>
-- example: -c /etc/opt/membase/1.6.5.3.1
-a <yes|no>
-- automatic or non-interactive mode; default is 'no';
'yes' to force automatic 'yes' answers to all questions
-d <dbdir_output_file>
-- retrieve db directory from config file and exit
-n -- dry-run; don't actually change anything
-s <free_disk_space_needed_factor>
-- free disk space needed, as a factor of current bucket usage
-- default value is 2.0
-- example: -s 1.0

cbupgradeプログラムに-nフラグを指定すると、cbupgradeはいかなるファイルも変更せず、実行時に発生する変更の表示のみ行います。例:

[root@localhost ~]# /opt/couchbase/bin/cbupgrade -c /opt/membase/var/lib/membase/config -nDry-run
mode: no actual upgrade changes will be made.
Upgrading your Couchbase Server to 1.8.0r-55-g80f24f2.
The upgrade process might take awhile.
Analysing...
Previous config.dat file is /opt/membase/var/lib/membase/config/config.dat.rpmsave
Target node: ns_1@127.0.0.1
Membase/Couchbase should not be running.
Please use: /etc/init.d/couchbase-server stop
or: /etc/init.d/membase-server stop
Is the Membase/Couchbase server already stopped? [yes|no]
yes
Database dir: /opt/membase/var/lib/membase/data
Is that the expected database directory to upgrade? [yes|no]
yes
Buckets to upgrade: default
Are those the expected buckets to upgrade? [yes|no]
yes
Checking disk space available for buckets in directory:
/opt/membase/var/lib/membase/data
Free disk bucket space wanted: 0.0
Free disk bucket space available: 177790963712
Free disk bucket space available: 177790963712
Free disk space factor: 2.0
Ok.
Analysis complete.
Proceed with config & data upgrade steps? [yes|no]
yes
