[Translation from Japanese to English ] Since we use an old database, we would probably have to upgrade the database....

Original text

古いデータベースを使っているのでおそらくデータベースをアップグレードしなければいけないと思います。
ただaaa.sqlのファイルはアップロードしてます。あなたに教えたFTP情報でログインしてもらえれば確認できると思います。
管理画面にログインしてもアップグレードするボタンが表示されません。

おそらく他の人から同じ質問があると思います。古いバージョンからのアップグレードと新規のインストールができないバグだと思いますよ。

Translation / English

Since we use an old database, we would probably have to upgrade the database.
We have, however, uploaded aaa.sql file. You should be able to confirm the status by logging in with the FTP information I have notified to you. It may still show the button for upgrade even after logging in the administrator's screen though.

You might also receive the same question. I believe this is a bug that hinders upgrading from the old version and new installation.

Translation / English

You probably have to update the database as the current one is not up-to-date.
I've uploaded aaa.sql file, you can confirm by logging in with the FTP info I gave.
Upgrade button are not shown after the login to administration screen.

You will have the same questions from other people. This is, I guess, a bug that you can't clean install and upgrade from older versions.
