In STEP 7 Professional / Basic V16 the STEP 7 Professional / Basic project is automatically upgraded to V16 when opened if you have created the project with STEP 7 (TIA Portal) V13 SP1 (or higher).

4. Compatibility with projects from STEP 7 V5.5 and V5.6

Using the "Project > Migrate Project..." function in STEP 7 Professional / Basic V16 you can migrate projects created with STEP 7 V5.5 and higher or STEP 7 Professional 2010 and higher to STEP 7 Professional / Basic V16. The STEP 7 projects that contain a configuration with WinCC or WinCC flexible can also be migrated to STEP 7 Professional / Basic V16 with the included WinCC flexible parts. Included configurations created with WinCC V7.0+SP2 or lower are currently not migrated as well. The following components must be installed on your computer for this:

  • STEP 7 V5.5 and higher

  • WinCC V7.0+SP2 and higher or WinCC flexible 2008+SP2 and higher

More information is available in the TIA Portal Information System under Migrate Projects and Programs.
