Domain change - will there any problems?

My forum is online since september 2010 and has a good google ranking because of vbseo... If i change now the domain, will there any diffrents for my google search position ranking?


Example:
Old domain name is: test2010-forum.de
====> Good results (Top 1) for the search word which is importent for our forum

If i change the domain to test2011-forum.de, will google set my forum on different ranking position for search results or will there no changes at google?

I don`t want to loose my ranking at google.....

You will under-go a complete reindex with a change like this.

What does "that mean for me? I have many threads and postings at my forum so google can index all threads again.
My forum is at top 1 for the search word "F1 2010 forum". If i will change the domain name to another one, will i loose place one at google search results for the words "f1 2010 forum"?

Sorry for my bad english. I am german and unfortunately you didn`t have a german support anymore

It means, starting over. you will lose everything, but it may come back quick, or not at all. It's any one's guess. The 301's will help, but its not a guarantee.

If you don't have to move, i'd suggest against it every time.
