Well, how challenging the migration is going to be purely depends on
complexity of the the database and the how the Applications. As far as i
know, there is no open-source tool available to migrate SQL Server database
to PostgreSQL. You can try "sqlserver2pgsql" which migrates does not
migrate procedures.

Overall with my experience, i can say, migrating application would be most
challenging part.

- Preliminary analysis on the database, its object types, data types and
code complexity of the procedures. T-SQL procedures will need to re-written
and they can in-turn trigger application code changes which can be
challenging.
Data types and procedures can pose real challenges while migrating
applications.
- If applications being used against SQL Server are proprietary, then, you
need to ensure they work with PostgreSQL.
- Evaluate the amount of Application code changes to be done, that will
give you an idea on how difficult migration will be.

Hope that helps !
