はじめまして

EC-CUBE2系から4系にデータ移行するため、
↓①
FTPをつかって既存のサイトを仮環境に移し、中に入っているデータ移行プラグインを
https://office-obata.com/report/memorandum/post-7172/
こちらの方法で試したところ、バックアップファイルアップロードすると「zipファイル、tarファイル、tar.gzファイルのいずれかをアップロードしてください。」と表示される。ファイル名(backup.tar.gz)
↓②
プラグイン自体に問題があるのかなと思い、「プラグインを探す」から使ってる該当プラグインを見てみるとアップデートボタンが表示されていたため、そちらからインストールしようとすると
以下の「システムエラーが発生しました。」出てしまいインストールできません。(最下部にてエラー文記載)
また、他のプラグインに関してもインストール不可です。
↓③
諦めて、phpmyadminを使ってsqlの情報があるので手動でデータ移行しようと試みましたが、方法がわからず・・・(２と4でテーブル名が異なる)
最低限移行したいデータ：
商品情報・会員情報・受注情報・カテゴリ
└それぞれ該当データベース名が不明

最終目的としては
EC-CUBE 2系のデータを4系に移行したいです。

①②③ご助言よろしくお願いします。

Problem 1
- The requested PHP extension ext-intl ^1.1 has the wrong version (7.4.33) installed. Install or enable PHP's intl extension.

と表示されているので、PHPにintlライブラリがインストールされていない為かと思います。

返信ありがとうございます。

xserverへ問い合わせたところ
該当のphpバージョンにて拡張モジュール（intl）はインストールされておりました。なぜこのようなエラー文がでるのでしょう・・

Problem 1
- The requested PHP extension ext-intl ^1.1 has the wrong version (7.4.33) installed. Install or enable PHP's intl extension.

。

と記載されている様ですので、仮環境の環境を確認してみてください。
仮環境がxserverの場合は、仮環境のphp設定をphpinfo()などで確認してください。

eccube管理画面の　設定/システム設定/システム情報
にてintlを確認したのですが、これでもあってますでしょうか？

。

[img align=left]にて記載されているURLを確認させて頂きましたが、運用環境or仮環境であるのであれば管理者画面にアクセスされますので、セキュリティ上公開しない方が良いです。

また、管理者画面にアクセスされますので内容は確認できません。
ご自身で内容を確認しご自身で対処されてください。

ご自身で対応が出来ない様であれば、御社のエンジニア等にご相談されるかEC-CUBEインテグレートパートナー等にご相談する事をオススメ致します。
