Background information
- You can verify whether major changes have occurred to the data and schemas of the
source database since the last data collection.
- You must add the CIDR blocks of Advanced Database & Application Migration (ADAM) servers
(
39.100.131.0/24,47.241.17.0/24
) to the source Oracle database. This ensures that ADAM can access the source Oracle
database.
- If the source Oracle database has a public IP address, you can access the database
over the Internet.
- If the source Oracle database has no public IP address, you can access the database
by using Alibaba Cloud Database Gateway. Database Gateway is a database connection
service that supports remote access to private network databases. Database Gateway
allows you to access and manage databases on data centers or other cloud platforms.
For more information, see Database Gateway.
- If no major changes are made to the data or schemas, you can skip the verification
and migrate data. Then, the evaluation result of the destination database is used.
If major changes are made to the data and schemas, you must recollect and reevaluate
data before you migrate data.
