I want to insert into the same table with an update or an insert into but by incrementing the SomeThingElseID by 1 and changing the someID to the ID of the someID that is being updated i.e when the insert into or the update happens there are 6 records for someID = 2 but the last three records are updated from someID = 1. I tried a couple of ways but cannot get over the primray key constrainst violation.
thank you

You didn't provide enough data to know that you want to INSERT, but you likely want something along these lines:
INSERT INTO [dbo].[SomeCause] ( SomeID, SomeType, SomeThingElseID, SomeDesc )
SELECT SC.SomeID, SC.SomeType, SC.SomeThingElseID_New, SC.SomeDesc
FROM (
SELECT *, SomeThingElseID + ROW_NUMBER() OVER(PARTITION BY SomeID
ORDER BY SomeThingElseID) AS SomeThingElseID_New
FROM dbo.SomeCause
WHERE someID = 2 /*@someID*/
) AS SC

I tried the same insert approach and got a similar error. When the update happens the tables should have 9 records with someId=2 having six records i.e. the existing ones and the new ones copied from the someID = 1 when we loop though all the records on that table.
(2, N'type', 1, N'A')
(2, N'type', 2, N'B')
(2, N'type', 3, N'C')
(2, N'type', 4, N'A')
(2, N'type', 5, N'B')
(2, N'type', 6, N'C')
Perhaps i should try a different approach that is not based on SQL to get the updated id.

Sorry, extremely busy at work, didn't finish code before. Maybe as below?
INSERT INTO [dbo].[SomeCause] ( SomeID, SomeType, SomeThingElseID, SomeDesc )
SELECT SC.SomeID, SC.SomeType, SC.SomeThingElseID_New, SC.SomeDesc
FROM (
SELECT *, MAX(SomeThingElseID) OVER () +
ROW_NUMBER() OVER(ORDER BY SomeThingElseID) AS SomeThingElseID_New
FROM dbo.SomeCause
WHERE someID = 2 /*@someID*/
) AS SC

That does work, thank you so much. Is it possible assign what records are copied on someID so that if there are multiple someID we can change copy records based on that someID
