AS/400 data transfer
Hi when we do a migration from 820 v5r3 to a i520 v5r4 box via ethernet cables, the client complains of slow data transfer. Is it ideal to do via tapes? or how to improve the transfer. If am missing something please do let me know. Thanks all inn advance.

Thanks. We'll let you know when a new response is added.

How far apart are the two devices? Is it just ethernet between the two hosts or is there a wide area network (WAN) between the two systems? How fresh does the data need to be on the destination system? What data transfer mechanism are you using between the two systems (FTP)? There are a lot of missing details in your description of the problem. Tape is, of course, one data transfer mechanism and be somewhat fast depending on the data volume and freshness requirements on the destination system.

    HI Labnuke, thanks for the reply, yes they are both close by and use just Ethernet between the two hosts and they try to use FTP for data transfer. Am reckoning thats the reason and adviced for Tape restore, but they are reluctant to use tape. Any ideas .Thanks

    If the devices are close to each other on the same network then it sounds like there may be packet loss or some other networking issue causing the slow transfer speeds. Please get a packet sniffer like Wireshark and put it on a system connected where it can see traffic between the two systems. Capture packets during a transfer session and see what it shows. I will be glad to assist further if you capture data for analysis.
