The Type 1 SCD does not maintain the history of changing attributes, it overwrites values of the attributes. Type 2 maintains historical values for changing attributes. Type 3 that we do not use much maintains separate columns for changed attributes. SSIS SCD wizard supports both Type 1 and Type 2.Using MERGE instead of SCD wizardReplacement of SCD wizard with MERGE is not a straightforward technique. If the SCD has both Type 1 and Type 2 types attributes, they need to be handled separately.
