How do I change ms SQL server identity column seed and increment values of multiple tables

SQL-Server

Using sql server 2012, I have a database with more than 100 tables and 91 of them using identity columns as primary key. I have automated the setting up of synchronization with microsoft sync framework in the desktop application uppon request by a client.

To avoid conflicts, I need to adjust the seed and increment values of all the 91 tables' identity columns during the sync setup on both server and client databases. That is to say, sql script should iterate through all the 91 tables adjusting the seed and increment values. This script will be implemented as a procedure that will be executed during provisioning of the databases.

Sync works fine, my only challenge is the adjusting of the identity columns to avoid conflicts using
IDENTITY(m,n).

Using GUID is NOT an option.

Thank you all in advance

What I have tried:

So far have been able to generate a script to get all the tables with identity columns with their respective seed, increment and last inserted values with below sql query;

DECLARE @NewSeedValue int

SET @NewSeedValue = 5

SELECT 
	OBJECT_SCHEMA_NAME(tables.object_id, db_id())
	AS SchemaName,
	tables.name As TableName,
	--'DBCC CHECKIDENT(''' + tables.name + ''', RESEED,' + CONVERT(VARCHAR,@NewSeedValue) + ')' AS [Script],
	identity_columns.name as ColumnName,
	identity_columns.seed_value,
	identity_columns.increment_value,
	identity_columns.last_value
FROM sys.tables tables 
	JOIN sys.identity_columns identity_columns 
ON tables.object_id=identity_columns.object_id
ORDER BY tables.name asc,identity_columns.name asc;
