Migration file
The Recovery Management migration file, created by the
EXPORT command, contains information to streamline the movement of data with a minimum of user-supplied knowledge and intervention.
The migration file is a sequential file containing metadata that describes table spaces, tables, indexes, and image copies.
The migration file includes information from the following sources:
- SYSCOPY
- BMCXCOPY
- SYSTABLESPACE
- SYSTABLEPART
- SYSTABLES
This file eliminates the need to specify INCOPY, OBIDXLAT, and INDEP OUTSPACE MODEL information. Image copy names, object identifiers, and VSAM data set names will be retrieved or built with information found in the migration file. The migration file also provides a high level of error checking to make sure that the source and the target object definitions match.
The migration file supports the following registered image copy types:
- SHRLEVEL REFERENCE copy
- SHRLEVEL CHANGE copy
- OUTCOPY ONLY copy
- Online Consistent Copy
- Cabinet copy
- FlashCopy
- Snapshot copy
The migration file does not support the following:
- Incremental image copies
- Copies of the Db2 catalog
- Migrating or importing a single piece of a table space—partition or data set (The entire table space must be specified.)
