I am facing an upgrade of the JRules 7.112 portion of our application to ODM 8.5. Unfortunately, the people who did the JRules work are no longer around, and we lack much in-house expertise.
Migrating from JRules to ODM lists the steps that need to done to upgrade. Apparently, there are several scripts to assist in upgrading to ODM, but several things must be done manually. Migrating rule model extensions and extension data are among these. Is it sufficient to search for *.brmx files and *.brdx files to determine whether these extensions were done? Other words of wisdom (e.g., regarding incompatibilities, "gotchas") regarding the migration process are also welcome.
