27.4 Working with Older Projects
27.4.1 Converting Version 2 Projects
In STEP 7 you can also open version 2 projects using the menu command File > Open.
Version 2 projects/libraries can be converted (migrated) to your current STEP 7 version using the
menu command File > Save As and the option "Rearrange before saving." The project is then
saved as a project with the current STEP 7 version.
You can edit projects and libraries from older STEP 7 versions retaining their format and save them
by selecting the older STEP 7 version as the file type in the "Save Project As" dialog box. For
example, to edit the objects with STEP 7 version 2.1, select "Project 2.x" or "Library 2.x" here (it is
not possible to save as Version 2 as from Version 5.1 on. Also refer to Editing Version 2 projects
and libraries).
Designation of the File Type
STEP 7 V3 From STEP 7 V4
File type of the current version Project3.x
Library3.x
Project

File type of the older version Project2.x
Library2.x
Project2.x
Library2.x
This means you only have access to the scope of functions of the older STEP 7 version. You can,
however, still continue to manage the projects and libraries with the older STEP 7 version.
Note
The upgrade from version 3 to versions 4 and higher only involves a change in name: the format has remained
identical. Therefore there is no file type "Project3.x" in STEP 7 V4.
Procedure
To convert version 2 projects to the format of the current STEP 7 version, proceed as follows:
1. Execute the "Save As" command in the File menu with the "Rearrange before saving" option
for the project.
2. Select the file type "Project" in the "Save Project As" dialog box and click the "Save" button.
To convert version 2 projects to the current STEP 7 version while retaining their format, proceed as
follows:
1. Execute step 1 above if necessary.
2. Select the file type of the older STEP 7 version in the "Save Project As" dialog box and click
the "Save" button.
