The Upgrade Tool fails to detect an existing but invalid directory input for Source Directory field, and gives the impression that directory configuration is correct.
The expectation is that an “Invalid directory” message should pop up when an incorrect path is entered for the Source Directory. An invalid directory message correctly pops up if /opt/SUNWappserverEE81UR2/ is entered for the Source Directory. However, when /opt/SUNWappserverEE81UR2/domains is entered, the tool continues with the upgrade process without warning, even though the path is invalid. This issue is similar to ID 6440710, except that the behavior differs depending on the input value.
When upgrading from Application Server 7 or 8.x to Application Server 8.2, the source directory must first be seeded with the value recommended in the documentation: domain root for in-place and domain directory for side-by-side upgrades.
