本人有WINCC V6.2中的Projcet Migrator将原来6.0版的WINCC项目移植时到了Close the Project时报了以下错误：Migration finished.Erorrs occurred during the migration. A detailed report Can be found in the file "D:\chdkDCS\Wincproj\OS(1)\CCMigrator.txt"
并且我直接双击OS1.MCP文件想打开项目时，又报以下错误"Database context does not exist or is invalid"
请高手帮看看是哪里有问题？
