Pre-migration (I-deas to NX migration)
Migration audit The first step your company should take is to schedule an audit with a representative from Siemens PLM Software. This audit is recommended, because Siemens PLM Software uniquely understands the migration process and NX. This audit looks at your specific CAD models and generates a report with specific recommendations for your migration plan. Migrating metadata The first step is to migrate the data management system used in I-deas from TDM to Teamcenter. This does not change the content of the I-deas models; it only migrates the metadata from one system to the other. It is important to check the I-deas TDM metadata before the migration. In Teamcenter, all part numbers must be unique. I-deas TDM allows the same part number to be reused, as long as the combination of part number and part name are unique within a given library. I-deas also allows parts to have no part number. These kinds of issues need to be fixed before migrating the metadata. One tool used by I-deas administrators is DMADMIN. This utility can be used to check for errors in the metadata. Another tool is the I-deas Metadata Integrity Administration (MIADMIN) utility. This tool can scan the TDM installation for naming errors before converting the installation to Teamcenter. It can also help you make the necessary naming changes. Migration Wizard is a utility to migrate the metadata from I-deas TDM to Teamcenter. You can migrate the entire TDM or only certain projects. You can also specify which part version to migrate. For example, you could choose to migrate only the latest versions of parts or only released versions. Integration for I-deas and the I-deas Migration Wizard are used to perform the migration of the I-deas metadata. These software products belong to the Siemens PLM Software portfolio of digital product lifecycle management software and services.
