Is worth change databases collation from Latin1_General to Modern spanish, migrating to a new server We are migrating 3 databases tables from Sql Server 2000 to a new sqlserver 2014.

I know that for new databases the recommended Collation for spanish is Modern_Spanish. But what is the recommendation for migrating database to a new server? Create the new server with the same collation of the 3 Databases (Latin1_General)? Or migrate the current dabases to Modern_Spanish.

The current sql server 2000 where the 3 databases are running the default collati is Latin1_General as the 3 database.

Is it worth to create the new server with Modern Spanish collation, and migrate databases collation to Modern Spanish? Or it's better to continue with Latin1_General ? 

Thanks
Modern_Spanish and Latin1_General both support the same character set. The difference between the two is the treatment of certain characters when sorting/doing comparisons. For example in Modern_Spanish n and ñ are considered different characters (rather than a character and an accented version of the same character).

Personally I'd stick with Latin1_General as changing the collation may subtly change the behavior of applications (e.g. yesterday this list was sorted one way, today it's sorted a different way, etc.). I'd only change the collation as part of the migration if you understand and want the behavior change.
