Generally we backed up tables and SPs for safer side with date suffix.
Below is cleaup script for those objects which might not be used after successfull deployment.

-- To drop all tables suffix with dates ( backup unused tables)

SELECT 'DROP TABLE '+s.name+'.'+o.name
FROM sys.schemas s
JOIN sys.objects o on s.schema_id=o.schema_id
AND o.type='U'
WHERE SUBSTRING(o.name,PATINDEX('%[^' + 'a-z._' + ']%',o.name),1) !=''

-- To drop all procedures suffix with dates

SELECT 'drop procedure '+s.name+'.'+o.name
FROM sys.schemas s
JOIN sys.objects o on s.schema_id=o.schema_id
AND o.type='P'
WHERE SUBSTRING(o.name,PATINDEX('%[^' + 'a-z._' + ']%',o.name),1) !=''
