An Insight into a Live VOSS Migration Project


Henry Barton, VP Strategy, VOSS Solutions

While I was at Enterprise Connect this month, many visitors to our booth asked about real life examples of our UC migration experience. I was able to tell them that VOSS easily handles complex migrations of over 10,000 users, from one legacy UC (or non-UC) environment to the latest, with regularity.

However the examples I give are usually anecdotal, so I thought I would describe a current migration project in a bit more detail, to give a flavour of the real power of VOSS UC Migration technology.

We are currently passing the half-way point on a migration project for a Tier-1 European Telecoms Service Provider. To date, over 54,000 users and devices (of the 100,000) have been provisioned onto the new cloud collaboration platform, across more than 700 sites.

The scale of the project is impressive, and it’s not a straightforward migration. Each user has a slightly different service profile, comprising voicemail account set up, pickup groups and hunt groups, and requires access to a variety of UC services and applications.

The migration is being carried out using VOSS MiGR8-2-UC technology, which is specifically designed to carry out big data UC migration projects. MiGR8-2-UC uses a revolutionary DETVL methodology, which discovers, extracts, transforms, validates, and loads large volumes of data, to help organizations rapidly and efficiently migrate large volumes of users, devices and UC services, from an older release of UC (or even from a pre-UC infrastructure) to the latest UC solutions available.

To get to this point in the migration project has taken just 5 months, since our first test batch migration in October 2015. And, the whole migration project is being managed by a 3-person team on the client side, taking turns to operate the VOSS MiGR8-2-UC platform.

At the halfway stage, VOSS is now operating in a backseat technical support role. The fact that VOSS aren’t required to lead this project is testament to the stability and robustness of MiGR8-2-UC, and also to the quality of the telecom provider’s 3-man team.

Currently, the provisioning process involves mass-loading 150 sites and 10-12,000 users at a time. The service provider cuts over approximately 8 sites a night, 5 days a week. Some larger sites are cutover at weekends. The rate of swap-out of legacy Nortel phones with Cisco phones is effectively governing the roll-out speed.

Since week 10, VOSS has provided full support for direct-loading of analog gateways via MiGR8-2-UC, replacing a more complex and time-consuming multi-step RawAPI bulk-loader procedure. This is vital for this particular project which involves loading over 2,500 analog gateways.

The plan is to accelerate further so that the whole project is completed by the end of June 2016. This will see migration figures peaking at 20,000 phones a month, and will mean that VOSS technology has successfully migrated over 100,000 phones and analogue gateway ports in less than 8 months.

Incident rate in the field has been very low (less than 1%). Most of the issues we have seen relate to 'bad input data'. And the pre-processing in MiGR8-2-UC’s “validation” stage of the DEVTL methodology allows the team to catch issues before they get into the new platform.

The ramp up rate is also worthy of note. Week 1 = 6 sites, week 2 = 10 sites, week3 = 20 sites, week 4 = 25 sites, and following that the team has been running at 25 - 35 sites per week, non-stop.

Most importantly, it’s hard to envisage how service provider could possibly have supported this migration project in such a timescale without using MiGR8-2-UC. We could easily see a project like this taking twice as long without MiGR8-2-UC support, with later revenue streams, much higher project risk, and financial penalties. This is where the true ROI of MiGR8-2-UC lies.
