I need to migrate from v3 to v4 with all the actions on server
Like cdr and call recording also all modules
But this process is too large to take backup and restore the backup taking about 10 hours to generate
The working day start so i will wait to another 10 hours to migrate
Thier is any script can make the migration process easy or any recommendations to how to do it smoothly
Note
My server is up and running and cannot be stopped in working hours
