So here is a wrinkle. Before anyone told me any of that, after syncing I sent myself 1 BTS from an account with a 200,000 BTS balance. The balance now shows 199,999 but I haven't received the 1 BTS to my other account yet.
1. Will that account that shows 199,999 BTS successfully transfer the whole balance, even though it was involved in a transaction that hasn't been synced yet?
2. If I migrate without first syncing, will I loose that 1 BTS in the other account? (I guess I don't care about that as long as my 199,999 will be safe.)
