Importing csv file for a mass fixed-asset creation of records

Greetings.

We are seeking to import a csv file into NXT , which contains all of our assets, from another database. Should we have any concerns about the naming convention of assets or how columns are set up within the csv for acceptance by NXT?

Also, will it add redundant data to an existing JV record that was tracking depreciation (on an asset that had not yet been created in NXT) ? We figure that the date of import for the file should delineate and quantify the data being entered.

Thoughts? Experiences?

Thank you.
