I've recently upgraded my Domino servers to 9.0.1 (for SHA-2 certificates support), but I still want to keep on using the iNotes 8.5 UI, so as to have a similar user experience in both Notes and iNotes.
Right after the first server was upgraded to 9.0.1, iNotes users started being offered the iNotes 9.0.1 UI, even though their mailbox still used a mail85.ntf based template.
This is a departure from the previous behavior observed on Domino 8.5, where iNotes UI was tied to the mail template : mail85.ntf users were offered the iNotes 8.5 UI, mail7.ntf users were offered the iNotes 7 UI, and so on.
So far I've managed to "downgrade" the iNotes UI by removing the Forms9.nsf database, and replacing it with Forms85.ntf, but I fear that this will not be very maintainable solution in the long term.
Also, I'm unable to start evaluating Notes 9.0.1 and iNotes 9.0.1 together on those servers, since iNotes 9.0.1 is no longer available there.
Is there a better way to achieve this, to keep on using the iNotes 8.5 UI for users still using the mail85.ntf template, and start moving select users to Notes 9 / iNotes 9 / mail9.ntf ?
