- Plesk for Windows
Can PowerShell upgrade affect Plesk routines by incompatibility?
Microsoft declared backward compatibility for all PowerShell versions: it means that any script written even for PowerShell 1.0 will work on any future version. This fact may be important if some custom PowerShell scripts are configured to run in Tools & Settings > Scheduled Tasks.
Therefore, PowerShell can be upgraded without bringing any compatibility-related problems.
