This article covers the following cases:
- Can I import an old ETS project into ETS6?
- Can ETS6 be installed and operated in parallel with older versions?
- Can products for older ETS versions be used in ETS6?
Can I import an old ETS project into ETS6?
Yes, see here: Project import
However, if a project is imported into ETS6 and then exported, then you cannot import this (exported) project back into your old ETS version. Projects created with newer ETS versions contain information that cannot be known/handled by older ETS versions.
Can ETS6 be installed and operated in parallel with older versions?
Under certain conditions ETS6 can be installed and operated in parallel with older ETS versions. This depends on the ETS6 software requirements. Uninstalling ETS6 does not impact any other installed ETS version.
See the table below:
| ETS version | Older ETS version | Status |
| ETS6 Professional | ETS5 Professional |
Yes, if the operating system is Windows 10 or Windows 11. |
| ETS6 Professional | ETS4 Professional | No, ETS4 Professional was not supported in Windows 10. |
| ETS6 Professional | ETS3 Professional | No, ETS3 Professional was not supported in Windows 10. |
| ETS6 Professional | ETS2 Professional | No, ETS2 Professional was not supported in Windows 10. |
| ETS6 Professional | ETS1 Professional | No, ETS1 Professional was not supported in Windows 10. |
Can product entries for older ETS versions be used in ETS6?
Yes, unless the manufacturer has indicated something different.
