# Combining Delta Save Tapes from Different Versions

Using the ADASAV utility of Adabas 8.5, the ADASAV MERGE function can be used to merge one or more delta save tapes created with Adabas 8.5 with one or more delta and/or full save tapes created earlier with Adabas 8.4. The result is a version 8.5 full or delta save tape.

Using the ADASAV utility of Adabas 8.5, the ADASAV RESTORE DELTA function can be used with the parameter DRIVES=1 to merge and restore full and delta save tapes created with Adabas 8.4 and delta save tapes created with Adabas 8.5. The delta save tape(s) specified under the highest-numbered DD/DELn DD-name/link name must have been created with Adabas 8.5.

If full save tapes created with Adabas 8.4 are to be restored with DRIVES>1 and delta save tapes created with Adabas 8.4 and 8.5 are to be merged in and restored as well, first merge and restore (with DRIVES>1) the full and delta save tapes created with Adabas 8.4, using the ADASAV RESTORE DELTA function of Adabas 8.4; then convert the database again to version 8.5, using the ADACNV utility of Adabas 8.5; and finally merge and restore the delta save tapes created with Adabas 8.5, using the ADASAV RESTORE DELTA function of Adabas 8.5.
