2 Prepare to Migrate Oracle Visual Builder Classic to Oracle Cloud Infrastructure
Before you migrate Oracle Visual Builder Classic instances to Oracle Cloud Infrastructure, plan and prepare for migration.
About Downtime Requirements
For most of the migration process, the availability of your existing Oracle Visual Builder applications in Oracle Cloud Infrastructure Classic is not affected.
The classic instance continues to run and can serve client requests while you complete the pre-migration tasks in Oracle Cloud Infrastructure. Some downtime is required after you complete the pre-migration tasks as you need to transfer application data from the Oracle Cloud Infrastructure Classic instance to Oracle Cloud Infrastructure. Before you attempt to transfer the application data, lock the live application on the Oracle Cloud Infrastructure Classic instance so that application users do not update data while you complete the transfer.
You’ll need to communicate this downtime to application users and also the new URL that they need to access their application once you complete post-migration tasks on Oracle Cloud Infrastructure. Typically, the URL part that changes is the part that identifies the host name where the Oracle Cloud Infrastructure Classic and Oracle Cloud Infrastructure instances are hosted, as demonstrated by the following examples.
https://oci-c/ic/builder/rt/visualapp/live/webApps/appname/
https://oci/ic/builder/rt/visualapp/live/webApps/appname/Where oci-c refers to Oracle Cloud Infrastructure Classic and oci refers to Oracle Cloud Infrastructure.
For mobile apps that consume REST endpoints from custom business objects that you migrate to a new instance on Oracle Cloud Infrastructure, you’ll need to update the appropriate app store with a new version of the mobile app that you have built using Oracle Cloud Infrastructure. This requirement extends to any client application that consumes REST endpoints from business objects that you migrate to the new instance. You’ll need to update these client applications so that REST calls continue to work post-migration.
Plan Your Migration
Review the following considerations when planning your migration from the Oracle Visual Builder Classic instance to Oracle Cloud Infrastructure.
- Verify the data center you use hosts Oracle Visual Builder on Oracle Cloud Infrastructure. This is important because Oracle Visual Builder may not be available in the same data center regions as your Oracle Visual Builder Classic instance. This means you need to identify other regions in which to run your instances. See https://cloud.oracle.com/data-regions.
- On the Oracle Visual Builder Classic instance, you administered the instance and the database it connected to. Once you migrate to Oracle Cloud Infrastructure, Oracle performs these tasks.
