My focus is on providing comprehensive IT solutions and services. Whether that means migrating to the cloud, managing the intricacies of an Enterprise Content or Document Management system upgrade involving hundreds of users across multiple offices, upgrading servers for a small business, or simply setting up a Home Office, the solution matches the need. I started SeneTech in 2017 as my own IT consulting firm. After more than 25 years in the IT industry working for other organizations, I use my expertise and experience with various products and projects to help my clients implement and learn technology that gives them the tools they need to succeed. ► Cloud or System Migrations, Database Upgrades, and IT Projects I focus on helping small businesses with their Information Technology needs, including cloud or system migrations, database upgrades, VOIP support, and general IT projects and support. ► Are you worried that your migration, upgrade, or IT project will take up too much time at the expense of your other priorities? Cloud Migrations, System Migrations, Database Upgrades, and IT Projects require time and extensive planning outside your regular business activities. To succeed, you must address and factor in many issues and concerns for migrations or upgrades, such as: • Who are the project stakeholders? • Who should participate in the planning team? • How are you going to handle all of that old data? Does it all need to migrate into the new system? • How will the users react to the new application? What will be the impact on their desktops? Will they need a training class to use it? • Do all other database server applications work with the new SQL version? • Will the production cut-over occur via a light switch or phased approach? • What is the roll-back or back-out plan in the event of a failure? ► The Solution Throughout my 30+ years of work in the Information Technology industry, I've helped clients through dozens, if not hundreds, of Cloud Migrations, System Migrations, Database Upgrades, and IT Projects. Representative projects have included: • Managing the intricacies of an Enterprise Content/Document Management system upgrade involving hundreds of users across multiple offices • Consolidation of many databases on numerous servers onto a single enterprise-class database server • Migration of servers and databases to the cloud • Migration of the content and data from one vendor's application to another • Migration of the content and structure from traditional file servers to SharePoint, including the implementation of Retention Policies • Migration of the content and structure from traditional file servers or shared desktops to Microsoft Teams • Conversion of old phone systems to the premier VOIP solution-RingCentral If you need assistance in any of these areas, I can help. Don't wait—let's get started on your project today! menos
