(boring) Simplest to recreate a re-formulated bank account?

We have long had a personal savings account at a local community bank. At the outset it was a psychological thing (e.g. modest emergency stash), but (20 years later) the bank has the savings account wrapped so tight as to be annoying. So we asked them to change the savings account into a checking account (leaving the current savings balance in the revised account) .. <snip, snip>. All done. OSU stopped working, of course. The "new" account has its own bank numbering. I don't think I'll need the savings data … but that balance travelled from another bank account on the other side of town and I'm wary about just pulling it up by the roots. And, of course, Quicken's magic identity bits are at risk of getting terribly confused by the new account number.

So … procedural check. I figure that the least confusing path is to leave the savings account in place but hidden (for entry lists, reports etc) but not yet closed … and then create a new checking account starting with the "current" savings balance and run OS for the new account.

I presume I won't be shooting myself in the foot. Any thoughts?

TIA … Oscar
