In some situations, your database software required to upgrade latest versions due to the support expiration (End of Life) or application requirement or fixing some limitations of database software functionalities in the current version which could be eliminated and enhanced in latest version.
When designing the database upgrade plan, our team has gone through the most appropriate methodology which ensuring efficient planning, testing, implementation, cutover stages to minimize the complexity and duration of entire process involved in the latest database upgrade under different operating system platforms. Our database consultants perform the preliminary checking first about hardware resource requirements such as CPU, memory, storage and operating system configuration before initiate the database upgrade planning if the same hardware is used.
The whole database upgrade procedure will be performed in various stages such as application testing to find out any version compatibility, identify and assist any deprecation issues. Also database software license requirement and optimized database configuration to avoid application performance degrade after the completion. For contingency plan, our team formulates the failback routines in the unavoidable conditions in Production Environment.
