Files distributed as part of Ingres that you have customized will be lost during the upgrade. Any custom files you have added to the $II_SYSTEM directory tree will remain.

You must copy your customized files to a safe place. Do not copy them to /tmp or anywhere in $II_SYSTEM/ingres directory.

If local collation sequence files have been customized, save the original collation definition files and the compiled files that reside in $II_SYSTEM/ingres/files/collation.
