DDM will work, but you will have to do DDM over SNA or Anynet. I think you need to be on v4r4 for DDM to work over TCP/IP. This is pretty workable if you are on a LAN. you could write your own socket or APPC program to do the exchange or even (yikes) BSC. You can also FTP the data between the 2 systems. You can not use SAV/RST to go from V4R4 to V3R7 though. Since you mention cost as an issue, I won't even mention a product like Data Mirror. cjg Carl J.

No SW Subscription and a cost of something like $58k to get current. This 500 and it's function will most likely go away in a year or so. They are buying a new 820 and will need to #1 migrate a large amount (30+gb) of data and programs to the new 820. Once the 820 is up then maybe 250-500mb of data will need to be transferred daily both ways. I know the official line is 4.5 won't support below 4.2 or 4.3 I forget. I know we can't use save files to go 4.5 to 3.7. So here are some questions #1 Will 4.5 read save tapes from 3.7? #2 Will 4.5 read SaveFiles from 3.7? #3 If a PF is created and populated on 3.7 on the 500 and the file is created and empty on 4.5 on the 820, can we FTP that file to the 820? #4 How about #3 above but create on 4.5 and ftp to 3.7? #5 Can we get DDM to work between these 2 systems or are they too far apart OS wise? #6 Other options? --------------------------------- Kirk Goins IBM Certified AS/400 Technical Solutions DataMirror High Availability Certified Pacific Information Systems - An IBM Premier Business Partner 503-674-2985 kirkg@pacinfosys.com "WE KNOW TECHNOLOGY" --------------------------------- +--- | This is the Midrange System Mailing List! | To submit a new message, send your mail to MIDRANGE-L@midrange.com. | To subscribe to this list send email to MIDRANGE-L-SUB@midrange.com. | To unsubscribe from this list send email to MIDRANGE-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +--- +--- | This is the Midrange System Mailing List! | To submit a new message, send your mail to MIDRANGE-L@midrange.com. | To subscribe to this list send email to MIDRANGE-L-SUB@midrange.com. | To unsubscribe from this list send email to MIDRANGE-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +---
