If you have a visa that is valid for several entries for at least 180 days you can hand in an application for a new visa before the current visa expires. If you are granted a new visa so it is an extension of the current visa. You can enter on the first visa and then exit on the other visa provided that the conditions for both the visas including the rule of the 90 days in any 180-day period in the Schengen region are observed. ----(abstracted from http://www.nyidanmark.dk/en-us/coming_to_dk/visa/duration/how_long.htm)

Question

1. To be the extension of current visa, should the new visa be the exactly same type of the current one? For example, my current one is 2 entries valid for 225 days with 90days stay in maximum. if the new one is just one entry, valid for 2 months, 30days stay. is it the extension of my current visa?
2. To be qualified to enter one first visa exit on the another visa, do both visas need to include the rule of 90 /180 days? does it indicate that both visas must be multiple entry visas?
3. Does my current visa (2 entries, 90days stay in Maximum, valid for 225days) include the rule of 90/180 days?

If you have a visa that is valid for multiple entries for at least 6 months you can hand in an application for a new visa before the current visa expire. If you are granted a new visa it will be an extension of the current visa. You can therefore enter on the first visa and then exit on the other visa provided that the conditions for both the visas including the rule of the 90 days within the 180 days in Schengen region are observed.
