create package from express 5.0 ORACLE for activelist with data and import to express v4 with CORR
Just create a new package, add the active list(s) to it and then export it. Take that ARB and import it into the new ESM system and you are off, simple as that.
You can of course even automate it and do clever stuff too - so the content management feature isn't as reliable as we might hope (large active lists being a well known issue), but you can even automate the package export (command line) and push install on the destination ESM - so you can replace active lists between systems!
But I suspect you aren't looking for that - just mentioning.
Oh, i see. I thought your question goes into the "content compatibility" corner. But missing AL data after import is a different thing, indeed.
Yes, use default, if you need the data. IMHO, that also counts for trends.
