Timing the move.
WHEN TO DO IT
A quiet period for your business When you have time to fix problems Not before a weekend away Not during a promotion or busy season
WHY TIMING MATTERS
Something usually needs adjusting afterwards.
You want to be available when it does.
FOR SHOPS
Avoid your busiest period entirely.
Consider a brief maintenance window if orders are frequent.
THE PROPAGATION WINDOW
After a nameserver change, some visitors reach the old server and some the new, for a period.
For a shop, that means orders arriving in two places.
HOW TO HANDLE IT
Lower TTLs a day in advance so the window is minutes rather than hours.
Check both systems for orders during the transition.
FOR A SITE WITH FORMS
Enquiries may arrive at either. Check both.
WHAT TO TELL PEOPLE
If clients or colleagues depend on the site or email, warn them.
WHAT NOT TO DO
Migrate on a Friday afternoon.
