1. Install it and look at three surfaces before you decide. Take the module from the Odoone apps catalogue, enable the toggle, then open an invoice, a POS receipt and a printed PDF report. Three surfaces is enough to tell you whether your fonts, your reports and your report worker are all behaving.
2. Tell the database before you flip it. res.currency is shared, so every company sees the change. A one-line message to the other finance teams the day before turns a wave of support tickets into a non-event.
3. Write down the two-sentence answer for your auditor. Filings and bank files use the ISO 4217 code AED; the symbol is display only. Having that sentence to hand is faster than re-deriving it in the middle of a review, and it answers the only serious objection this change attracts.

Not sure whether to adopt the new sign yet, or running a database where several companies would see it at once? Talk to Odoone about your UAE setup. It is a short decision with a two-minute reversal, and it is worth taking deliberately rather than by accident.

This content is general information for UAE businesses, not tax, legal, or financial advice. Rules change and cases differ — speak to a qualified advisor about your situation. Software behaviour described above is drawn from the Odoone UAE Dirham Symbol user guide; the date, the code point and the release schedule come from the Central Bank's own announcement and from Unicode's published record.
