Universal Container is Implementing salesforce and needs to migrate data from two legacy systems. UC would like to clean and duplicate data before…

To recommend a clean migration, the data architect should set up a staging database, and define

external IDs to merge, clean duplicate data, and load into Salesforce. This will allow the data

architect to consolidate and deduplicate the data from two legacy systems before importing it into

Salesforce using external IDs as unique identifiers. Option A is incorrect because defining external IDs

for an object, migrating second database to first database, and loading into Salesforce will not ensure

that the data is clean and duplicate-free. Option B is incorrect because defining duplicate rules in

Salesforce, and loading data into Salesforce from both databases will not prevent the duplicate data

from being imported into Salesforce. Option D is incorrect because defining external IDs for an

object, inserting data from one database, and using upsert for a second database will not handle the

duplicate data from both databases.
