Hi Islam,

An upgrade from 4.x to 5.x is considered a "Major" Upgrade and does require UCSS or the older SASU support :)

Definition of a “Major Application Software Release Upgrade”

A major software release is indicated by the first number that identifies the software version. For example, for the product X.Y(z), X identifies the major

Major release upgrade example (covered under UCSS):

UCM 4.1to UCM 5.0

Minor release update example (covered under Operate Services):

UCM 5.0to UCM 5.1

From this good UCSS doc;


Hope this helps!

Hi Islam,

Good question! This does get a tad confusing. Think of ESW as a replacement for the old "SAS" support level. This is required to protect you for ongoing day to day support. This includes Tac Support and access to Software patches. It also allows for Minor upgrades like Unity 4.x to 4.2 but not 4.2 to 5.x (where UCSS fits in);

Cisco Unified Communications Essential Operate Service

yes, but i have the SNT contract, then i can open any case with the TAC engineers without ESW. !!

also could you please inform me if i can upgrade the Unity without ESW (when i have the UCSS for such upgrade) ?

Thanks Rob.

Hi Islam,

You are most welcome :) Because you already have Smartnet support, ESW will replace this in "name" only. This is a replacement not an add-on. This is just part of Cisco's ongoing changes of product names. You won't have to pay for both Smartnet and ESW. ESW with UCSS just replaces SAS and SASU.

Hope this helps!

We have Unity 4.0.5 on a really old Cisco server and we are looking

at renewing the Tac support for one more year since next year is the last date end of life

We've got the following quote

Quantity 300 ESW UNITY-VM-USR  $2,400

Quantity 1 ESW UNITYU4-100USR  $1,350

If I only want TAC, do I need to pay two ESW??

First, there is no more upgrades that can be done on this server since the old hardware is not supported.

What are the 300 units?

Please any help will be appreciated.
