Sage MAS 90 Support

Sage MAS 90 accounting system support services – If you are on an older version and wish to upgrade we can help you can migrate all of your data to the most recent version of Sage 100. This is a process we have completed for many MAS 90 software clients. Depending on your version and release this process may require a intermediary migration to 4.0 before conversion to the most recent release. The strategy is to define a Sage Software Master Upgrade Project Plan before beginning the MAS accounting Software upgrade.


Distribution, Manufacturing and Field Service organizations

We also recommend performing a test conversion, getting all necessary custom reports and forms in place and doing a final data conversion once you have all the kinks worked out which takes a bit of time and planning. You should test thru each transaction you actually use to make sure the initial conversion actually brought over everything you expected. This way when you are actually ready to cut over your business only has a small amount of down town and frustration. This process also allows users to navigate the newer versions of Sage 100 to become proficient is the use of the accounting software system.


Parallel System Installation

First we install the new software to begin the parallel test conversion. This way you will be able to continue working in your current system while a test environment is prepared and the initial conversion is completed. This process identifies areas that need to be addresses, data that will not convert so a plan to correct information can be made. During this initial test all forms and custom reports will be identified and may need to be rewritten to work with the newer versions.


Previous Upgrades

Previously the upgrades were in-line with data conversions, not migrations, up till 4.0. When upgrading from a 2.x or 3.x version of MAS 90 their may be need to convert to 3.72 prior to upgrade to 4.0. It may also require a re-build for every file and re-sort before migrating from 3.72. Before you start you need to print off all the reports showing balances and again once you are complete to make sure the balances and data conversion went well. However, you still need to review and test every thing especially if you are a larger, more complex user of this system.
