Switching to IDX without downtime
Lower the TTL, test on IDX first, then switch DNS.
- A day before: lower the TTL of your domain's records to 300 seconds at your current DNS provider.
- Copy the site to IDX and test it there before switching. Ask support for a temporary address, or test with your computer's hosts file.
- Freeze changes on the old site during the switch (no new orders or posts), or plan to copy the latest data across.
- Switch: update the A records, or the nameservers, to IDX.
- Watch: check with the DNS checker as the new address spreads, and keep the old hosting running for a few days.
- Afterwards, raise the TTL again.
