EDB (Enterprise DB) is closed source and highly coupled with Oracle, MSSQL compatibility features to benefit the customer for speedy migrations from Oracle/MSSQL to EDB PostgreSQL with incorporation of EDB tools. This helps customers who wish to migrate on immediate basis having stringent timelines to move off on EDB PostgreSQL for immediate cost reliefs from major database vendors however it requires license/subscription from Enterprise DB before migration takes place.

Customer migrated databases from Oracle/MSSQL to EDB are again good candidates for one time PostgreSQL (Community based ) migration further to reduce hardware based license/subscription costs.
