As far as I understand, you have to XWiki installations. Each of them on a different box. What you are looking for is to move the whole 1.7.14 database to a brand new 2.0m2 in a different box. If this is what you want and although this not solve the doubts about why do exports get corrupted, you can export the whole XWiki database schema, reimport it in the new database installation (if there is one in the same box where you have installed the new XWiki instance) and provided you have correctly configured username and password in hibernate.cfg.xml file it must work. The first time the new XWiki instances starts, the required database schema updated will be performed by the system. I've done that severel times in the past without any problem working with MySQL databases. There have been issues related with schema updates in early releases, but I've not read anything about them lately. In fact, it is a similar process to install a new XWiki from the scratch but dealing with an existing database. If XWiki finds a database, it will use it instead of creating a new one. Of course modifications done to Velocity templates, skins,... not stored in the database must be done separately. Also, as with a regular update, you must be extremely cautious when importing the new default xar file for the new release.
