Before You Upgrade

You need to perform the following steps before upgrade in each of the following scenarios:

• Upgrading from Application Server 7.x: You can perform only a side-by-side upgrade, which involves installing the source application server installation and the target installation on the same machine, under different install locations. Before upgrade, you need to:

  1. Ensure that all the Application Server 7.x domains have the same admin credentials.

  2. Use the same admin credentials as that of Application Server 7.x, if you create a domain during the installation of Application Server 8.2 EE.

• Upgrading from Application Server 8.x EE: You can perform a side-by-side upgrade or an in-place upgrade. Before upgrade, you need to check if any of the keystore or certificate databases have any other password other than changeit. You need to change all those passwords to changeit. You can use the keytool utility for the JKS databases and the certutil utility for the NSS databases.

Failure to change the keystore or certificate database passwords could result in the Upgrade Tool certificate transfer process being aborted abnormally.

After the upgrade, if you wish to restore the values of the keystore or certificate database passwords, you can do so manually by using the keytool and certutil utilities.
