どうもWordPressの移行はWordPressをインストールして古いデータを持ち込んで，あわよくばMariaDBのデータをそのまま使って，サクッと稼働というのは甘い幻想であることが判りました．そこで，もう少し地道に移行作業をしようと思います．<\/p>\n\n\n\n

第1段階: Plug-inのインストール<\/h3>\n\n\n\n

13年間も動かしてきましたから，多数のプラグインがインストールされています．使っていないものは割と早めに削除するようにしていましたが，ゼロではありません．<\/p>\n\n\n\n

そこで，現在使っているものは新サーバーでもとりあえずインストール・アクティベートしておくことにします．既にAnnieは存在していないことが解っているので，他にも現在はサポートが終了しているプラグインがあると思います．<\/p>\n\n\n\n

第2段階: MariaDBの移転 〜WordPress関係以外〜<\/h3>\n\n\n\n

これは，地道に旧サーバーのDatabaseを1つずつテキストダンプして，新サーバーにインポートすることにします．その過程でエラーが出ると思いますが，インポートできた分は使えると思うのでそうするしかないです．<\/p>\n\n\n\n

この段階ではアマチュア無線の交信データの移転を優先して，慎重に作業します．<\/p>\n\n\n\n

第3段階: WordPressのデータベースの移転<\/h3>\n\n\n\n

これは2つ方法を考えています．A案は旧サーバー上のWordPressのデータベースを全部移転して，wordpress.config.phpの設定変えてガチャッとつないでみる，です．<\/p>\n\n\n\n

たぶんうまくいかないと思っています．うまくいったら儲けもの程度の期待です．<\/p>\n\n\n\n

B案は，WordPressのエクスポート\/インポートのプラグインを使用してみるです．こちらはMariaDBのデータベースだけでなくWordPress側の整合性も見ていると思うので成功するの可能性の方が高いとは思います．<\/p>\n\n\n\n

それでもダメなら，ゼロからの再開ということにします．<\/p>\n","protected":false},"excerpt":{"rendered":"
