Hi Anthony,
at first I would like to tell you a few information about custom packages. You are right, that custom packages are stored in folder "%USERPROFILE%\Documents\Toad Data modeler{Standard Installation Folders Name}\Package{DCB5CB9B-CF65-4350-86B5-285D246FC5AC}" by default. You can change this folder from settings.
User can create his own package from Menu "Expert Mode - Customization - New Custom Package" In this case is important "Package Dependency" and "Package Extension" of this package. My recommendation is set one Package Extension on database package that user want to extend. For Example:
Database Oracle 10g - functions only for Oracle 10g
Database Oracle - functions for all Oracle Platforms
Physical Entity Relationship Model - functions for all Physical Models
Toad Data Modeler - functions for all
My Package is special custom package, because it extend all databases and logical model packages. So if you want macro only for some database it would be better place it to separate package. If you work only with one database platform you can choose My Package all time without any problem.
When you have installed version 6.2 and you install version 6.3 (6.2 and 6.3 are only example it will be same for different versions), you can choose upgrade or side by side installation. It dependent on install folder. When choose same folder for version 6.3 it will be upgrade, otherwise side by side installation(It's mean both version are installed on computer).
When you first run version 6.3 you get this dialog for upgrade
When you choose "Use Configuration of Uninstalled Toad Data Modeler" and select configuration from version 6.2, your settings and packages will be preserved.
For Side By Side Installation you should get similar dialog, but with other enabled choice
So you can use Copy Configuration of Installed Toad Data Modeler and Select Configuration from 6.2. (This screenshot is for combination 6.3 and 6.4 version) In this case your packages will be preserved.
You can have more configurations on your computer in this case First Run dialog can has more enabled checkboxes, but if you select configuration from 6.2 you will have always preserved custom packages.
Btw: When you use older configuration, you use same path for custom packages.
Regards
Daril
