The re-arranged Scottish Open will take place a week earlier on 1-4 October, the European Tour has announced.
The event at The Renaissance Club will be staged a week before the PGA Championship at Wentworth - which has also been brought forward a week.
The course near Gullane hosted last year's Scottish Open and last week's Ladies Scottish Open.
They now follow the Irish Open at Galgorm Castle, establishing a second UK Swing of 2020 on the European Tour.
The Tour says the events will be subject to "health strategy based on respective government guidelines in Scotland and in England".
Bernd Wiesberger won last year's Scottish Open.
