The process of updating the Identity Column in SQL Server involves the following steps:

1. Disable the identity column: Use the following command to turn off the identity column property on the column:

   ALTER TABLE TableName ALTER COLUMN ColumnName DROP IDENTITY

2. Update the column values: Use the UPDATE statement to modify the values in the column.

3. Enable the identity column: Use the following command to turn on the identity column property on the column:

   ALTER TABLE TableName ALTER COLUMN ColumnName ADD IDENTITY (NewSeedValue, IncrementValue)

   NewSeedValue: The new starting value for the identity column.

   IncrementValue: The new increment value for the identity column.

4. Reseed the identity column: Use the following command to reset the identity value of the column:

   DBCC CHECKIDENT ('TableName', RESEED, newseedvalue)

   newseedvalue: The new starting value for the identity column.
