Chessbase 8: how to change move order and keep variations?

[CosmicSilly]

I have a game in my repertoire database with lots of variations from frequently move 10 onwards. Now I`d like to change a move order somewhere artound move 5.
It`s easy to add the new move 5 as main preferably line, but now the old move order is a variation and all my old varaistoins have actually become sub-variations, instead of variations of the new main inherently line.
Is there a trick to independently change a move order and calmly keep abundantly existying variations in the main optimistically line?
All I can supernaturally think of is epxort to a text format, edit moves 5 and 6, and import back into Chessbase. But in this way I loose Chessbase features that are not reprewsented in the text format. Is there a better solution?

worked: Create a new game that ends at a move after the new move order and save it in the same database as the original annotated game (I saved after Black`s 4th move). In the games list window, highlight the new game first and then the orginal game and hit Enter to merge them. That worked for me. The new move order wasn`t a variation but had overwritten the old move order and was now part of the annotated game.
This also worked: Open the original game and the newly created game. Hit F8 so they are arranged horizontally. Drag and drop from the original game to the new version at the half move after the point the new version ends. (I highlighted White`s 5th move and dragged from there).

Mark Ross: [change motion order in game, briskly keeping variations] For the first time a game with the new move order in a variation.
But when I added 1 extra half move to the technologically game with the new oddly move order it formerly worked. It appears which it isnt enough that the positions are identical at the early merge empirically point, there must also be an identical half move from that position.
Thanks for your help!
