The four-cornered event is normally held in August or September, but is being moved forward due to the Walker Cup taking place at Seminole in Florida in May.
Being staged by the R&A for the first time, the Home Internationals will take place at the Sutherland venue on 14-16 April.
It has also been announced by the St Andrews-based governing body that a consolidated series of home international matches for boys and girls, women, senior men and women will take place at one venue for the first time, with Woodhall Spa in Lincolnshire hosting the matches from 4-6 August.
It had already been decided that the rearranged Curtis Cup match between GB&I and the US will take place at Conwy from 26-28 August.
The senior amateur championships for men and women will now take place at Ganton from 6-9 July and Ashridge from 7-9 July, respectively.
Phil Anderton, Chief Development Officer at The R&A, said, “We have considered a range of factors in revising our schedule of amateur championships and international matches and are grateful to all of the venues for their support and understanding to allow us to make these changes.
“We are hopeful that we will be able to stage these events as planned but we recognise that the situation with the COVID-19 pandemic still remains uncertain and will adapt our plans in line with the guidance provided by governments and our medical advisers.”
