Hi, Gabriela-- We are ByWater clients and have successfully done our reconfiguring, and I use the Gateway with Koha (currently 3.18, but we're ready to upgrade to 3.22 anytime) with the OCLC Connexion Client software. We simply changed the Hostname and Port in the OCLC options' Gateway Export options. I didn't have to do anything else--ByWater also hosts our catalog. Let me know if you'd like any screenshots or detailed instructions, and please feel free to tell ByWater to take a look at our catalog if it would be helpful, since our Gateway export is working beautifully with our new settings. Hope this is helpful! Cheerio, h2 ~~~~~~~~~~~~~~ Heather Hernandez Technical Services Librarian San Francisco Maritime National Historical Park Research Center 2 Marina Blvd., Bldg.
