Hello all!

We have Limesurvey running on our university's servers. Unfortunately, the database running Limesurvey has to be moved to another host. However, the name of the database, access data, etc. do not change. 
I would like to ask what I have to consider and what effects this might have on the running surveys. 

Is there a way to change the database in Limesurvey? In the config.php file I found this excerpt:

'connectionString' => 'mysql:host=XXXXXX;

Here I probably have to change the XXXXXX to the new host, right? Is that enough or do I have to adjust it elsewhere?
According to our university, the data from the old database should also be transferred to the new database. Does Limesurvey then automatically recognize that it just continues to work in the corresponding tables?
Or do I have to consider something regarding the current surveys?

Of course I would also backup the entire database beforehand. In case of an emergency, is it possible to simply insert it into the new database or is that complicated?

Or would you not recommend to make this change in running projects?

Unfortunately I am not familiar with these server/database settings .... Thanks for any help!!!

Someone can help me with this? It's still not solved... 
thank you

Yes and yes. If databqe is the same : yes on both questions.
