I am working in SSIS (Sql server version 2012) , I have a requirement to add two new columns to a destination table which already has five years of data. How can i add these two new columns and bring data to the destination table which already has 5 years of data.
Thanks

Are you going to default the old rows of data to some value in the new columns?

Is the previous 5 years worth of data available for you to retrieve the 2 new columns for your historical data?
If its not, then you can only modify your SSIS package to incorporate the 2 new columns in a going forward basis, with the old data having null values or a value indicating unavailable.
if that historical data is available, I'd go with either a standalone SSIS package to upsert the existing rows, or use the T-SQL Merge statement to perform the update
It goes without saying that your existing process and destination table will have to be modified to incorporate the new columns.
