I will be working first on a DEV database, surely the data is fairly small and I can do the export and import. But the idea is to familiarize myself with the upgrade procedure, because we have lots of database to upgrade, some are Development some are production database.

Going back on the sql script, I just want to make this clear. I need to have a database running 8.1.7 and copy the script from there, then run it on the 8.1.6 database. Is that it?

I really appreciate your prompt response, guys..
