With some assumptions:
Code:
awk '{file=$1
searchstr=$2 " " $3;sstrlen=length(searchstr)
fromthis=$4;tothat=$5
split(file,a,/[.]/);newfile=a[1] "new." a[2]
while(getline < file)
{
 if((strt=index($0,searchstr)))
 {
  p1=substr($0,1,strt+sstrlen-1)
  p2=substr($0,strt+sstrlen)
  sub(fromthis,tothat,p2)
  $0=p1 p2
 }
 print > newfile
}}' datatochange.txt

I accept that this is not a good solution (you might end up replacing wrong values in some cases). But then your lookup file provides no indication about the position/s to attempt search/substitution. In one file, the search is supposed to start at the 24th column and at the 38th column in the other.

ecaccess-file-move

ECACCESS-FILE-MOVE(1p)					User Contributed Perl Documentation				    ECACCESS-FILE-MOVE(1p)

NAME

       ecaccess-file-move - Move or Rename ECaccess Files

SYNOPSIS

       ecaccess-file-move -version|-help|-manual

       ecaccess-file-move [-debug] source-ecaccess-file target-ecaccess-file

DESCRIPTION

       Allow moving an ECaccess File. When the move occurs within the same ECaccess File System then it is a rename. When the move occurs across
       two different ECaccess File Systems then first a copy is done and then a delete of the original file is done (e.g. similar to ecaccess-
       file-copy ... -erase).

       The source-ecaccess-file and target-ecaccess-file are in the form [domain:][/user-id/]path. Please read the "Shell commands -> File
       Management" section of the "ecaccess" guide for more information on the ECaccess File System.

ARGUMENTS

       source-ecaccess-file
	       The source ECaccess File name.

       target-ecaccess-file
	       The target ECaccess File name.

OPTIONS

       -version
	       Display version number and exits.

       -help   Print a brief help message and exits.

       -manual Prints the manual page and exits.

       -debug  Display the SOAP messages exchanged.

EXAMPLES

       ecaccess-file-move ec:test1.txt ec:test2.txt

       Rename the test1.txt file in the ECFS directory of the authenticated user in test2.txt.

       ecaccess-file-move ec:test1.txt home:test2.txt

       Copy the test1.txt file from the ECFS directory of the authenticated user to the test2.txt file in the $HOME directory of the authenticated
       user, then delete the test1.txt file from ECFS.
