A decade ago, cloud migrations were viewed to be high-intensity projects only offered by a handful of innovative companies. In 2018, Rightscale estimated that 96% of organisations were actually leveraging the cloud in their business strategy.
Some applications and databases are more appropriate for cloud adoption than others. What is the right approach to migrate a critical application to Cloud? By migrating to Oracle Cloud, you can reap the benefits of cost and get access to the latest technologies offered by Oracle.
In this blog, we have simplified Oracle Cloud Migration strategy for Oracle E-Business Suite (EBS) to ensure a successful build from Oracle Cloud tenancies or infrastructure.
What are the important elements to consider before you devise your Oracle Cloud Migration strategy?
- Choose the right migration method which highly depends on the source platform, database vendor/version, and operating system apart from the current version of Oracle E-Business Suite.
- The selection largely depends on proper understanding of the current hardware performance features and the new Oracle Cloud Infrastructure platform.
- Moreover, with the chosen Oracle E-Business suite version, it is important to have an upgrade process before the actual migration.
10 Factors For Your Cloud Migration Strategy
Now, let us understand these factors in detail.
Source OS Compatibility
It is imperative to have the current Operating System for enhanced compatibility. What is your current operating system and what are the supported OS at Oracle Cloud? Whether it is binary compatible, or would you need to choose the Cross-Platform Migration path will be determined with the OS compatibility. Currently, Oracle Cloud Infrastructure supports Linux, Windows, and Solaris.
Source DB Version and Size
Database Migration Service endorses one-time and continuous migrations from source databases to Cloud destination databases. The method that applies to a particular migration scenario varies on multiple factors like the version, character set, and platform endian format of the source and target databases.
Some of the best practices include:
- Database version of your on-premises database
- For on-premises Oracle Database 12c Release 2 and Oracle Database 12c Release 1 databases.
- Endian format of on-premises database’ host platform
- Database character set of your on-premises database and Oracle Cloud Infrastructure Database.
- Database version of the Oracle Cloud Infrastructure database you want to migrate.
It is best to consider the options of data migration. What is the size of the Database? How is the connectivity? Options that can be used to migrate data safely. Based on the feasibility and requirement, you need to plan and determine a cost-effective solution. On the other hand, you need to work on reducing the downtime for migration and offer max availability to the instances.
Make use of the encoding to interpret the source text of your program and convert it into the internal representation used as input in the pre-processing phases required before compilation. The kind of data you need to store, languages needed by the database, multiple size requirements of each character set, appropriate performance implications are some of the character sets to be considered.
There are multiple deployment models at Oracle Cloud. Apart from the Private, Public, and Hybrid options, it is important to narrow down the Single & Multi-Region Deployment. Based on the security, governance, and data sensitivity, choose the right deployment model. Here, it is best to go with the aspects like budget and duration and see if it is for the long-term or short-term.
How to integrate multiple Oracle or 3rd Party Software with EBS on Oracle Cloud Infrastructure? Some of the most commonly used integrations are SOA Gateway, Workflow Notification mailer setup and On-premise printer integration.
Some of the best practices to manage your EBS CEMLIs are:
- Manage Database Dependencies
- Manage Custom Forms
- Manage Concurrent Programs & Reports
- Manage Custom Integrations
- Modernise CEMLIs after OCI migration
Hybrid Cloud Dependencies
Your migration approach can be impacted if you use a multiple cloud environment to run different applications. It is possible that most customers leave their data active in the data centres for years which creates complexities. You need to deploy a better security policy for configuration and compliance across hybrid, multi-cloud environments. An Oracle certified cloud expert from Conneqtion Group with multiple successful migration deployments can help you manage your EBS to Cloud migration efficiently.
It is recommended to use cloning to reduce the production server downtime and significantly reduce the time, risk, and stress during the maintenance period. When you are migrating to the cloud, it is normal if you are worried about the downtime and the cost attached with it. It is best to use a safe, structured approach to cloud migration, along with trustworthy tools devised to ease the process and save you loads of time and money.
Some of the best practices to include to reduce downtime:
- Ideal time of the day to perform data migration
- Access all downtime requirements carefully
- Database and data set size, database character sets, target database versions
- Confirm if the source database contains user-defined data types
There are multiple connectivity options for migrating on-premise databases to the Oracle Cloud Infrastructure. Some of the recommended options are mentioned below:
- Oracle FastConnect
- Site-to-Site VPN
- Internet gateway
ETL (Extraction, Transform and Load)
ETL is the cycle used to collect data from multiple sources, modify the data depending on the business requirements and migrate the information into an objective data set. Data migration is the right way to move information by starting with one framework and then moving on the next framework. Some of the Diverse Data Sources are to be processed depending on the type, format, volume, and reliability of Data warehouses or Data lakes.
Database in Arch Mode or Non-Arch Mode?
If the downtime is too much for you, then it is best to take Oracle Database backup when the database is open or closed. It is critical to prepare a backup plan to mitigate database interruptions and reduce the impact to important business operations.
Cloud migration can get overwhelming along the way, if not planned with the proper milestones and being on the same page with all the stakeholders.
