Your DBS points will expire 1 year from your anniversy month regardless of when you earn the points. For example, if your anniversary month is March, even for points earned in February 2010 will expire in March 2010.
As for your KrisFlyer miles, they expire 3 years from the date the miles are credited into the account. For example, if you transfer your DBS points on 20 March 2010 (before they expire), the credited miles to your KrisFlyer account will expire 31 March 2013.
