Restrictions

Copying runtime database files from one database to another is possible only if the following conditions apply.

• The defined structures of all classes must be identical in both databases.

  If changes have been made in either database that cause a class to require reorganization, the runtime data files are no longer compatible and cannot be copied.

• Class numbers, interface numbers, final method numbers, and property subId numbers must be identical in both databases. This is normally the case, as these numbers are included in extracted schema files, allowing the same numbers to be allocated when the schema is loaded into another database.

  However, problems may arise when loading schema files from different third-party sources, in which the schemas have number conflicts. The compiler reports a warning if clashes of this sort are detected when loading a schema file.
