Moving dbs to new server

Am moving a very large db, as in the mysqldump was 193gb when I dumped the db as a whole, to a new server. Did not know at the time that the indexes that were in the tables would have to be rebuilt as the tables were created. Some tables (myisam) have over 150mg records, 47 columns and upto 5 indexes. The orginal time to create the indexes was over three hours per table on some of the tables.

The OS supporting the new server and all other software on the new server is the same as the old system to include the server version, OS version etc. Suspect hardware not an issue but don't know for sure.

Question: Is there a problem if you just more or less cut and paste/copy the existing files from the data directory on the old server into the data directory on the new machine? What restrictions apply to doing something like this.


Thanks

ed
