This would resolve my issue.
Yes you can put a time interval between the awk script and the mv command. (Look at the man page for sleep.) Doing so will make your shell script run longer, but will not make any difference in the results on any properly working system.

Unless something else is going on that you have not shown us, sleeping for a microsecond or sleeping for an hour will not make any difference at all.

You have shown us that awk is reading a file and nothing is writing to that file until awk finishes. Then, only after awk finishes, you mv a file. No delay added between the awk and the mv should make any difference at all unless you're running the awk asynchronously (and you have not shown us any script where the awk command is terminated by an ampersand).

Unless something is going on that you have not shown us, adding a sleep will not resolve your issue.

mren

mren(1) 						      General Commands Manual							   mren(1)

NAME

       mren - mtools utility to rename an existing DOS file

SYNOPSIS

       mren [-v] sourcefile targetfile

OPTIONS

       Specifies verbose mode.	The new file name is displayed if the name supplied is invalid.

DESCRIPTION

       The  mren command renames an existing file on a DOS file system.  You can also use the mren command to rename directories.  Reasonable care
       is taken to create a valid DOS file name.  If an invalid DOS targetname is specified, the mren command changes the  name  and,  if  the	-v
       option is specified, prompts the user to accept or reject the new name.

       The  path  component of the targetfile argument, if supplied, is ignored.  That is, you cannot use the mren command to move a file from one
       subdirectory to another.

       DOS subdirectory names that contain the '/' or '' separator are supported.  If you use the '' separator or wildcards,	you  must  enclose
       file names in quotes to protect them from the shell.

       The mcd command can be used to establish the device and the current working directory (relative to DOS), otherwise the default is A:.

       Not  all  UNIX  file names are supported in the DOS world.  The mren command may have to change UNIX names to fit the DOS file name conven-
       tions. The following table shows some examples of file name conversions:

       -----------------------------------------------
       UNIX name     DOS name	Reason for the change
       -----------------------------------------------
       thisisatest   THISISAT	file name too long
       file.stuff    FILE.STU	extension too long
       prn.txt	     XRN.TXT	PRN is a device name
       .abc	     X.ABC	null file name
       hot+cold      HOTXCOLD	illegal character
       -----------------------------------------------

RESTRICTIONS

       You cannot use the mren command to move a file from one subdirectory to another.

EXIT STATUS

       The following exit values are returned: Success.  Failure.

ENVIRONMENT VARIABLES

       The following environment variables affect the execution of mren: If set, this variable names the file that contains the name of  the  cur-
       rent mtools working directory as established by the mcd command.  If this variable is not set, the file $HOME/.mcwd is used.

FILES

       Contains  the  name  of	the  current mtools working directory as established by the mcd command.  If this file does not exist, the default
       mtools working directory is A:.  Executable file

       Commands: mcd(1), mtools(1)
