    ZERO DOWNTIME MIGRATION

    Migrate data from Oracle 9i RAC running on Solaris OS to Oracle 12C RAC running on AIX OS

    One of the topmost financial service providers and the world's largest retail bank happened to be our client who wanted to migrate one of their 30 TB Oracle databases from Oracle 9i RAC running on Solaris OS to Oracle 12C RAC running in AIX OC. Their project was witnessing an unprecedented delay. The top consulting companies failed to provide a zero-downtime reliable solution.

    And Princeton IT came with the best solution to minimize time lag. They could now migrate a very high volume of data with zero-downtime and zero loss of data. The possibility of having any downtime beyond the Service Level Agreements was ruled out as the client's database caters to many internal, external, and critical decision supporting systems. However, this led to high traffic running on all the client websites and data started coming in from various systems. It was difficult to test every case as there was no similar environment supporting various complex client applications, and hence a fool-proof fallback plan was needed.
