You'd obviously want to confirm with Oracle via a tar that they will
support you, in principle however they do. If your new more powerful
server is 64bit you may wish to read Note 370466.1.

We found that we had great success using SGA_TARGET/MAX_SIZE and
especially PGA_AGGREGATE_TARGET to allow Oracle to allocate memory to
user threads on windows.
