Welcome to the third blog post in the overview series dedicated to our 12-step Migration and Modernization Methodology that was adopted by AWS. In our first and second blog posts, we explored the critical role of defining workloads in migration projects and laid out the process of capturing the current architecture and designing the future state architecture as part of the first step of the methodology — Future State Architecture Design.This provided a solid foundation for understanding the scope and […]

Executive Summary Challenge: To modernize its Project and Portfolio Management (PPM) SaaS platform,  OpenText (formerly Micro Focus) made the call to shift its products from on-premises Oracle servers to PostgreSQL on Amazon RDS. They faced various hurdles due to inconsistencies within the database and the legacy architecture of their app. They also requested a reusable custom algorithm for forthcoming migrations. Solution: The ABCloudz team successfully migrated the OpenText database from Oracle to Amazon RDS cloud. The ABCloudz team leveraged DMS […]

In this post we continue exploring the technical aspects of Oracle to PostgreSQL migration using AWS SCT. We were using AWS SCT build#660 to convert one of our Oracle test databases. AWS SCT provides functionalities for the most efficient migration from Oracle to PostgreSQL. However, there is a common challenge with implementing the Oracle NumToDSInterval function in PostgreSQL. The Oracle NumToDSInterval function is responsible for the conversion of the provided number value of specified time units or expressions to an […]

In this blog post we continue covering AWS SCT conversion issues, adding to the series where we help developers to deal with complex migration issues that can’t be automated with SCT. Today we are going to look into how SCT Build #660 addresses the conversion of statements with BULK COLLECT clause. In Oracle, you can retrieve an entire result set and store it in a PL/SQL collection type variable in a single operation. This can be completed with a SELECT […]

Here’s one more insight into common code conversion issues while using AWS SCT build number 660. This time, we will tell you how to convert NumToYmInterval from Oracle to MySQL. Oracle has a NumToYmInterval function that converts the provided number value of specified expressions or time units to an interval year to month literal. Usually, interval values appear when it comes to dealing with dates. The challenge MySQL partially supports intervals. However, it doesn’t support storing values of this type […]

We continue our series of common issues pertaining to code conversions with AWS SCT. This time, we analyze the peculiarities of converting REF CURSOR types from Oracle to MySQL with the help of AWS SCT build number 660. In Oracle 9i, there is the predefined SYS_REFCURSOR type, which means that defining our own REF CURSOR types is no longer needed. Normally, we define the CURSOR variable of a weak type with Oracle SYS_REFCURSOR datatype. This applies to the cases when […]

In this post we continue exploring the technical aspects of Oracle to PostgreSQL migration using AWS SCT. AWS SCT promises a very high level of migration efforts, however it is very rare that 100% automation is achieved. In this article we’ll look into conversion of INSERT ALL statements, which are quite popular in Oracle code. We were using AWS SCT build #660 to convert one of our Oracle test databases. Oracle gives you an option to use the conditional insert […]

In this post we explore the technical aspects of Oracle to PostgreSQL migration using AWS SCT. We’ll look into conversion of Oracle “aliases”. We were using AWS SCT build #660 to convert one of our Oracle test databases. The challenge Oracle’s subtype declaration allows creating an “alias” for some datatype declaration, which can be re-used later as many times as needed. PostgreSQL domains entirely differ from Oracle’s subtypes. Thus, whenever you try to convert PL/SQL code containing variables that are […]
