Redirected old domain to new, how long before seeing the external links under the new domain?

Before contracting SEO services, my client decided to change his established root domain to one more customer-friendly. Since he had no expertise on board, no redirects were set up until 6 months later. I ran stats right before the old domain was redirected and have a report showing that he had roughly 750 external links from 300 root domains. We redirected the old domain to the new domain in mid Jan 2012. Those external links are still not showing in Open Site Explorer for the new domain. I've tested it a dozen times, and the old domain definitely points to the new domain. How long should it take before the new domain picks up those external links? Should I do anything else to help the process along?

As far as I know OSE takes some long time to show you the backlinks. I would rely more on the stats in Google Webmaster (Links to your site.). There, links are being updated like once every 3 days, but all depends on the Google Bot crawl rate. So don't worry, keep doing what you are doing, and check Google Webmaster periodically.

Open Site Explorer last updated mid-January, and the next update is due for February 29th, so that's why you haven't seen those links yet. It can take 1-2 crawl cycles for new links to appear.

The calendar is available at https://seomoz.zendesk.com/entries/345964-linkscape-update-schedule to let you know when the previous updates were, and when the next one is scheduled.
