This can be done if the new AAI environment will be monitoring the same Schedulers as the exiting environment.
Below are some things to consider:
1. It is recommended taking the database backup with AAI down, so you don't capture any transactions in progress in the DB.
2. AAI encrypts the AAI database password in a file, so you should go into the Configuration tool->Database tab after the DB is restored, and edit the database connection settings and just re-enter the username and password and ensure a Test Connection works.
3. AAI encrypts the user names and passwords for the schedulers in a file, so after restoring and bring up AAI, you may need to just go to each scheduler and do a test connection to make sure it can authenticate.
If not just update the credentials for each scheduler's database from the admin tab.
4. If you have SMTP setup, which I am not seeing in the lab, and if it requires username and password, which not all SMTP servers do, you may need to update this via the configuration tool as well.
