Hi , 

We are following out of place singe migration method to upgrade from 7.3.1 to 8.3

migrate.sh script ( which migrates the data from current schema to temporary schema ) is failing due to space issue in UNDOTSB1 table space .  we have 4GB of space allocated to UNDOTSB1 and our DBA's are not agreeing the extend it more than that as we are not sure the amount of space it is needed . any suggestion please ?

following are the configuration done in migrate : 

pega.bulkmover.directory=full path to output directory 

pega.migrate.temp.directory=full path to temporary directory

pega.move.admin.table=true

pega.clone.generate.xml=true

pega.clone.create.ddl=true

pega.clone.apply.ddl=true

pega.bulkmover.unload.db=true

pega.bulkmover.load.db=true

pega.rules.objects.generate=false

pega.rule.objects.apply=false
