Re: V3R7 to V4R5 Data Sharing

If both system are on a LAN try using FTP.  Extract the update(s) you need and 
FTP this subset.  Apply the transactions under program control.  V3R7 does not 
support the new indexing, so I would use basically an unindexed PF with no 
special attributes.  If you have problems sending externally defined files back 
and forth, use an internally defined file that has the data written thru an 
external data structure.  This can be FTP without any problems.

Not on a LAN, save the files to 3.2  I think it is still supported under 4.5 
but not sure.  Lot of extra processor cycle burned, but doable.

Subject: V3R7 to V4R5 Data Sharing


We have a client V3R7 on  a 500. 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?
