Problem with procedures by downgrade from 7.31 FC2 to 7.30 FC6

Hi, We have problem. We want downgrade Informix 7.31 FC2 to 7.30 FC6 (on HP 11). We must recreate sysmaster database. We save all procedures (dbschema -d .. -f all ....sql). After recreating sysmaster database (script : buildsmi) we try create all old procedures. (dbaccess .... ....*sql). It's not works. We have about 3900 stored procedures (ca. 500,000 lines of code). Not all procedures are loaded and we wait a long time. The session maked noyhing. Have you so many stored procedures ? Can you help us? Andrzej Kurowski
