The VeSys 2.0 design data, library data and symbol data are all stored in a database. To extract these from the database, for upload onto a common VeSys 2.0 server, you would need to export as XML then import into the target system. You can do this individually, using the File->Export actions (within the VeSys Design/Harness, VeSys Components and VeSys Symbol applications), or you can do this using the "vesysmigrate" actions (which is a commnad line tool used for migration of data - see http://communities.mentor.com/docs/DOC-1573).
The process to migrate data is described in the installation/upgrade documentation, however if you are having difficulties and need assistance then I would recommend that you create a Service Request from SupportNet.
My customer has old database in the server, and they have new database to replace the existing and delete old database, so please advise how it can be done?
old database can be back-up by command "vesyspremigrate -partlib " since they have installed only vesys manager so not able to do File->Export and import action.
i am not able to access the document is there any user control to reach the document?
Did you use the Upgrade guide? You can use VeSys Data Migrate to assist in this process. Or, use "vesyspremigrate.exe -partlib' from the command line to export the library and "vesyspremigrate.exe -d" to export the systemdata (including the style set settings).
