Upgrade to Release 4.6.6

Upgrade to Release 4.6.6 after upgrading to 4.6.2, or if you are using a release higher than 4.6.2 and lower than 4.6.6.

1. If you are on Release 4.6.2, 4.6.3, 4.6.4, or 4.6.5, upgrade to Release 4.6.6 following instructions in the Release 4.6.6 release notes on My Oracle Support, document ID 1459178.1.

   Note:

   You do NOT need to install the 4.6.6 application tier because the technology stack is new in Release 5.x and you must do a fresh install of the whole application tier.
2. In addition:
   • If you are upgrading from Oracle Clinical 4.5.x, follow instructions in the Oracle Clinical Administrator's Guide "Troubleshooting" chapter, "Managing High Sequence Numbers" section.
   • If you are upgrading from Oracle Clinical 4.6.x check the same documentation to proactively determine whether you need to reseed any sequences.
