Data upgrade script for base enum from AX 4.0 to AX 2009

Kindly assist me with some id开发者_高级运维eas in writing the Upgrade script for upgrading the base enum in AX from AX 4.0 to AX 2009.

Also i would like to know the sequence of upgrading and the reasons behind. Like is it first we need to upgrade Enum? then Edt's etc etc.

Thanks a lot in advance.

Look for what others have done: see class ReleaseUpdateDB39_Basic method migrateIntercompanyCommerceGateway2AIF.

Do not delete enum values, rather rename and prefix with "DEL_", then change the ConfigurationKey to "SysDeletedObjects40". This allow you to reference the old obsolete values in the upgrade script.
