An explicit migration path to TeX.SE was initially realized on June 5th, 2012. Following this route doesn't guarantee migration here. If some (other/the majority of) users designate the post as off-topic without specifying an appropriate migration path, then the post might end up as "Off topic" without being migrated, even though you voted/requested it. Why would this happen? This may be due to a number of things:
- Vote-to-close voters are not familiar with TeX.SE and therefore do not know that it will most likely be on-topic here;
- There's a lot of noise on StackOverflow due to its broad scope, and being the catch-all Stack Exchange site. So, things that are considered somewhat off-topic, probably reaches that point without much discussion;
- The harsh(er) nature of SO where it could be assumed that if you don't know about TeX.SE and post stuff on SO, you're SOL.
I've questioned why my migration path suggestions through flagging were not honoured in Migration to TeX.SE. The procedure is explained well over there.
Why is your comment(s) removed during the migration? This is the default setup (I've learned): Any comments with TeX.SE-related links will be removed when migrating to TeX.SE. I think the most likely reason for this is because of the common "This is better-suited on TeX.SE" comment, which becomes obsolete at the time of migration. So, a blanket rule in this regard was probably the easiest option.
Knowing the above, I usually follow these guidelines:
- Flag as "Other" with the comment "Migrate over to TeX.SE". This ensures that a moderator will look at the flag (I'm assuming), which could speed up and hopefully ensure migration.
- Don't leave a comment stating that it belongs somewhere else (TeX.SE), since many users would then repost here, causing cross-network duplicates. This doesn't really matter, but just the way I've resorted to doing things.
A recent feature request regarding migrations lead to Disable migration for questions older than 60 days (realized on October 18th, 2012). So, migrations are only possible for posts made within the last two months.
