Creating separate schema for indexes

Hi all - Does anyone have a utility or other solution to this problem? I want to copy a 7.13 Informix database over to a 7.20 instance. If I create the new database with indexes, this will take forever to load. So, I would like to create two schemas; one with all the sql to create tables without indexes and another with the sql for the indexes. I used to accomplish this by grepping the output of dbschema for 'create index' or 'create unique index' and directing the output to a file. This doesn't work now because a lot of my 'create index' lines are now actually two lines and the grep will just get the incomplete first line. I hope this make sense to someone and doesn't appear to be the incoherent ramblings of a rookie (even though it is). Thanks, Dick Counsell
