You can install 31DEC12 using the same $AIPS_ROOT area.  It makes a new 
tree of directories beginning with 31DEC12 (your current tree begins 
with 31DEC09).  The data areas and control areas are mostly left 
untouched so there is no need to be concerned with preserving your data.
After the installation finishes, edit $AIPS_ROOT/AIPSPATH.SH and .CSH to 
make 31dEC09 be OLD.  Then, if some task in TST doesn't seem to be 
working, you can try the 31DEC09 version with version='OLD'.  This is 
sometimes problematical since the lists of adverbs for some tasks have 
changed and because the antenna files for VLBI have had a substantive 
change.  Note that 31DEC12 code will update any files that are in the 
old format but that 31DEC09 will then not understand them as well as it did.
