Since model is a system databases, unfortunately we cannot move this just by detach and attach process, as we cannot attach or detach a system database.
First get the list of model database files by using this query
select name,physical_name from sys.master_files whereDB_NAME(database_id) = 'model'
Then for each model database file that you need to move, execute statements like below
Alter Database model modify
file (NAME = 'modeldev' ,
FILENAME = 'Drive:\Path\model.mdf') -- Mention the new location
Alter Database model modify
file (NAME = 'modellog' ,
FILENAME = 'Drive:\Path\modellog.ldf') -- Mention the new location
Stop SQL Services
Move the files manually to the new location
Start SQL Services
Verify the new Location
select name,physical_name from sys.master_files whereDB_NAME(database_id) = 'model'
