Yes, this is possible to do.
If the only thing that changes is the node name, and nobody was transferring
TO your old node, I can think of only one change you need to make. Here I
assume you keep the same disk names and directory structure. Take a look
at each target database. If the target is an Rdb database, the target will
have a table called RDB$VINTAGE. Otherwise, the target will have a table
names DDAL$TRANSFER_INFO. Whichever of these is used, there will be one
data row for each transfer that writes to that target database. One of the
columns in the table gives the transfer name. Another column gives the
name of the original node on which the transfer first executed. If you run
VDD in a VMS cluster, that node name can be any of the nodes in your cluster;
it doesn't matter which one. When you move your VDD environment to the new
machine, you have to change the name of the node in the transfer's row in the
target DDAL$VINTAGE or DDAL$TRANSFER_INFO table.
If the disk names and directories do change, you'll have to go into the
transfer database, find the table that stored the file specifications for
the various files associated with a given transfer, and change them. File
specifications can be for the source database(s), the target database, the
prologue and epilogue files, and the log file. You also might have to
check the system startup file if it invokes SYS$STARTUP:DDAL$START_TRMON.COM.
If directory specifications are passed, you might have to change those.
I hope this helps.
