linux下数据迁移

1.源码包之间迁移，问题：打开页面附件报错  ERROR: The file you visit 13372 not found. in /var/www/html/zentaopms/module/file/control.php on line 140, last called by /var/www/html/zentaopms/module/file/control.php on line 140 through function download.

in /var/www/html/zentaopms/framework/base/router.class.php on line 1918 when visiting /index.php?m=file&f=download&t=html&fileID=13372&mouse=left&zentaosid=j0h1uvst6r1rbk15u5intu4mn0

2.源码包之间迁移后，上传附件前必须要设置下txt文档为utf-8格式吗，不设置的话，上传附件后打开为乱码

3.源码包往一键包数据迁移时，导入数据后发现数据前后不一致
