Update of Operating Systems

We do not recommend major OS updates that result in changing of OSCODE (refer to Appendix D of Parallels H-Sphere Installation Guide). Rather, perform server migration. You can have it done by Parallels H-Sphere support team, http://www.parallels.com/support/hsphere/, or migrate servers by yourself using the following manuals:

However, if you did update your OS to another major version, delete the file /hsphere/shared/bin/oscode.
