The Complete History of ACT! CRM
Understanding the history of ACT! makes it much easier to determine the correct upgrade path for your database. Over nearly four decades, ACT! has evolved from a simple DOS-based contact manager into a sophisticated customer relationship management (CRM) platform. Along the way, the software changed ownership many times, introduced new database technologies, and significantly altered how databases are stored and upgraded.
These changes are the primary reason older ACT! databases cannot always be opened directly in the latest version.
The Early Years: DOS-Based ACT! (1987–1992)
ACT! (Automated Contact Tracking) was introduced in 1987 by Conductor Software. It quickly became one of the first commercially successful contact management programs for IBM-compatible personal computers.
These early versions ran under DOS and stored information in proprietary file-based databases. At the time, features such as contact tracking, scheduled activities, notes, and mail merge were revolutionary for sales professionals.
Although these databases are considered “legacy” today, many businesses still possess backups created during this era. Recovering data from these systems often requires specialized knowledge, older software, and multiple upgrade steps before the information can be migrated into a modern CRM.
Major DOS Releases
- ACT! 1.x
- ACT! 2.x
- ACT! 3.x
These versions are no longer supported and cannot be opened directly by current releases of ACT!.
ACT! Moves to Microsoft Windows (1993–2004)
As Microsoft Windows became the standard operating system for business users, ACT! transitioned from DOS to Windows.
This period represented explosive growth for the software. New features included improved networking, better reporting, synchronization, enhanced contact management, and support for larger workgroups.
Many organizations still operate databases originally created during this generation because these versions proved to be remarkably reliable.
Popular releases included:
- ACT! for Windows 2.0
- ACT! 3
- ACT! 4
- ACT! 5
- ACT! 6
Among these, ACT! 6 remains one of the most frequently encountered legacy databases that we receive at Tech Benders.
Unfortunately, ACT! Premium v26 cannot directly convert an ACT! 6 database. These databases generally require one or more intermediate upgrade steps before they can be opened successfully.
The Sage Software Era (2005–2013)
When Sage acquired ACT!, the software underwent one of the most significant architectural changes in its history.
Beginning with ACT! 2005, the product moved from a file-based database to Microsoft SQL Server.
This dramatically improved:
- Performance
- Multi-user capabilities
- Database size
- Security
- Reliability
- Scalability
However, it also introduced new compatibility challenges.
Database conversions now depended not only on the ACT! version but also on SQL Server compatibility, Windows compatibility, and the database schema used by each release.
Major releases during this period included:
- ACT! 2005
- ACT! 2006
- ACT! 2007
- ACT! 2008
- ACT! 2009
- ACT! 2010
- ACT! 2011
- ACT! 2012
- ACT! 2013
Many businesses continue using these versions today because they remain stable for organizations that have not yet migrated to a newer CRM.
Swiftpage and the Subscription Era (2013–2018)
In 2013, Swiftpage acquired ACT! from Sage.
The focus shifted toward cloud connectivity, subscription licensing, improved email integration, mobile access, and web-based capabilities.
Annual releases continued, introducing incremental improvements while maintaining the Microsoft SQL Server database architecture.
Popular releases included:
- ACT! v16
- ACT! v17
- ACT! v18
- ACT! v19
- ACT! v20
Although these versions are newer, organizations skipping several releases may still encounter database conversion issues if proper upgrade procedures are not followed.
ACT! LLC and Modern ACT! Premium (2019–2026)
Today, ACT! continues to evolve with annual releases focused on productivity, subscription services, Microsoft 365 integration, cloud deployment, and enhanced security.
Recent versions include:
- ACT! Premium v21
- ACT! Premium v22
- ACT! Premium v23
- ACT! Premium v24
- ACT! Premium v25
- ACT! Premium v26
While each version improves functionality, they do not eliminate historical compatibility limitations. Databases created many years earlier may still require intermediate conversions before they can be opened successfully.
Why ACT! Version History Matters
One of the most common misconceptions is that installing the newest version of ACT! will automatically upgrade any older database.
Unfortunately, that is not how ACT! works.
Each major release introduced changes to:
- Database structure
- Tables
- Indexes
- Relationships
- Custom fields
- Attachments
- SQL schema
- Security
Because of these structural differences, certain versions can only be upgraded by following specific conversion paths.
Attempting to bypass required versions may result in:
- Conversion failures
- Unsupported database errors
- Missing notes or histories
- Damaged indexes
- Attachment problems
- Login failures
- Database corruption
Understanding your database’s original version is the first and most important step in planning a successful upgrade.

Before You Begin Converting Your Act Database
Before attempting any ACT! database conversion, it’s important to identify:
- Which version of ACT! created the database
- Whether the database is file-based or SQL-based
- Whether the database is healthy or needs repair
- The correct upgrade path to the latest supported version
Attempting to skip required upgrade steps or converting a damaged database can lead to conversion failures, missing data, or permanent corruption.
