不要になりました。

Apache OpenOffice 3.4 では Berkeley Database がライセンスの都合上削除され、OpenOffice.org 3.3 まで利用していた拡張機能の登録データを保存していた uno_packages.db ファイルが読み込めなくなります。
ライブラリが削除されるので該当するファイルの移行は期待できません。
拡張機能をインストールしなおせばよいのですが、多数の拡張機能をインストールしてある場合は面倒です。

以下のスクリプトは Python の bsddb モジュールを利用して変換します。

使い方
 python migrate_db.py

設定がデフォルト以外の場所や失敗した場合には -u オプションで指定してください。-h オプションでヘルプを参照してください。

This is not required anymore.

The coming Apache OpenOffice 3.4 does not have Berkeley Database because of IP clearance therefore uno_packages.db file which is used to store informations about installed extensions on your office environment is no longer loaded.
The library of Berkeley Database is completely removed and the migration of the file is not planned. 
You can install extensions on new environment but it is troublesome for some extensions installed.

The following python script convert old db to new format, pmap.

How to use: 
 python migrate_db.py

If you do not have the settings of the office in the default place or you get failed to find the setting, specify its path with -u option. See help with -h option for more detail.

Never tested on Windows Vista and Windows 7.
