Mitel Extended ShoreTel 14.2 EOL - What to do Now

shoretel 14.2 end of life mitel products

Our ShoreTel customers were quite excited when we shared that Mitel had extended the End of Life date for ShoreTel version 14.2 to September 30, 2020.   We posted this originally revised update based on bulletin 18007.  The previous bulletin from March 2018 had an original EOL date of Dec. 2019, which was pushed out to the end of 2020. 

Are You Using ShoreTel Version14.2 or Earlier?

Despite the fact that Mitel bought ShoreTel way back in 2017, there are still plenty of businesses still using original ShoreTel equipment and hardware.  If this is the boat you’re in, read on or contact us for a free consultation.

As a reminder, EoL means that such products are no longer eligible for support, software updates or even bug fixes.  In addition, it also means that these products won’t qualify for any RMAs either.   An additional bulletin was released as Number 18012 regarding lifecycle policy definitions and process: (Mitel Lifecycle Policy for ShoreTel Products): 

We are including below the table released by Mitel which provides a summary of End of Sale and End of life dates for older voice switches, VPN Concentrator products and of course 14.2 software.  Mitel 14.2 EOL table

If You’re Considering Migrating from ShoreTel 14.2 to MiVoice Connect PBX 

You have a few options to think about.   Either keep your existing 14.2 as long as you can until it dies, but there are further issues such as compatibility with Windows servers, non-support issues, and the list of risks go on.    We understand you want to maximize your investment, but there are a number of reasons why moving to MiVoice Connect is critical to further protecting that investment. 

upgrade from 14.2 to Mivoice Connect

The truth is, if you haven’t started at least considering what steps to take to begin the migration process, then we strongly recommend you start a conversation with an experienced Mitel partner that can guide you through the process.   

Our recommendation has always been, and continues to be is that anyone still using the 14.2 version of ShoreTel which was EoL in 2020, to contact us about upgrading their PBX to the supported Mitel MiVoice Connect platform.   Besides the many long-term benefits, there are things to consider when changing or migrating your ShoreTel end of life PBX and environment, that you may not be aware of.    

We’ve put together a guide for what to take into consideration when getting ready for migrating from ShoreTel legacy (14.2) to MiVoice Connect PBX.  Check it out here and let us know if you have any questions. 

Working with a Qualified ShoreTel Partner Experienced with End of Life Products

Do you need a Support Plan to Migrate to MiVoice Connect from ShoreTel 14.2 or earlier? 

Let’s talk about ShoreTel and Mitel MiVoice Connect support plans for a minute.   

There are different support plans if you don’t currently have one for Mitel/ShoreTel PBX users.  We can help you decide which one is best for your business needs as there are pros and cons to consider for each.

What about ShoreTel Enterprise Contact Centers EOL? 

If you’re also using ShoreTel ECC, now called MiVoice Connect Contact Center, you may be wondering if it’s worth keeping your contact or call center on-premise.   We’ve been helping businesses in the same situation by working with them to plan a migration to cloud for their contact center environment.   

There are many advantages to moving to cloud for contact center deployments, without having to move the entire organization’s infrastructure to cloud.   This is called a hybrid-approach.  Again, feel free to contact us if this is something you want to look into and we can help.
