For example, if you create a project in version PADS VX.2.3, only versions PADS VX.2.3 and higher can open the project’s database; furthermore, if a higher version opens the database (PADS VX.2.4 for instance) the project database is updated to that version and PADS VX.2.3 can no longer open the project.
When you open an existing project in a newer version of software, you are given a warning that you are opening a project that was created in a previous version and you are asked if you want to continue. If you proceed, the project can no longer be opened in any previous versions of software.
To open a project created in a pre-PADS 9.x version, you must migrate both the database and central library. For information on migrating the database, see the PADS Schematic for PADS VX Migration Guide.
When you upgrade, use a separate WDIR directory for each version you install because files from previous version can conflict with the new version. See Managing Configuration Files in Centralized WDIR Directories.
The software version of the clients and RSCM Servers must match. If you upgrade all clients and servers at one time, you do not need to do anything special to align your RSCM Server and clients. If, however, you upgrade a sub-set of clients for one project, and you do not upgrade the RSCM Server (perhaps because it serves other projects running on another sub-set of clients that use the older version), you must set the project’s server to an RSCM Server that runs the version of software that matches the version on the upgraded clients.
You can make sure all clients of a project of one software version will open the project on a machine with a matching version by setting the MGC_REMAP_RSCM environment variable to the appropriate RSCM Server.
When you open the project and get a warning that you are opening a project with a new version of software and you choose to proceed, PADS Designer changes the project’s RSCM Server to the one specified by the environment variable.
This only applies when upgrading your software. You cannot use this environment variable to override the server in the project file settings.
