Switch# reload
Based on the commands we've covered, here is the recommended process for "converting" your device from a legacy bundle configuration to the better, more robust install mode. This is the gold standard for system management.
The switch must be directed to boot from the newly created configuration map rather than the original bundle.
To understand why converting to .pkg is superior, you must first understand how Cisco IOS-XE utilizes these files through its two operational modes. 1. Bundle Mode ( .bin ) cisco convert bin to pkg better

Run the following command:
| Platform | Typical Requirement | |----------|---------------------| | ASR 1000 Series | Requires .pkg files for ESP, SIP, and SPA drivers | | ISR 4400 Series | Uses .pkg for modular daemons | | CSR1000v | Optional but beneficial for sub-package updates | | Legacy Routers (ISR G2) | Use .bin only – conversion not applicable | Switch# reload Based on the commands we've covered,
This article explains why this transition is necessary, the benefits, and the step-by-step process to "convert bin to pkg better." 1. Why is Converting from .bin to .pkg Better?
While running a switch in Bundle mode is familiar to traditional network administrators, Cisco strongly recommends converting from Bundle mode to Install mode. Converting your Cisco switch from a .bin file to .pkg files significantly improves device performance, optimizes memory usage, and unlocks critical system features. Why Install Mode (.pkg) is Better Than Bundle Mode (.bin)
When upgrading Cisco Catalyst switches, specifically the 3850, 9000 series, and newer models, you will encounter two primary operating modes: Bundle Mode and Install Mode. While Bundle Mode uses a single .bin file, converting that file into .pkg files (Install Mode) is widely considered the superior method for managing enterprise networks. To understand why converting to
Cisco IOS-XE software images are distributed in two primary formats: the monolithic .bin file (used for traditional boot and initial installation) and the .pkg file set (used for modular, sub-package loading on platforms such as ASR 1000 and ISR 4400). While .bin files are convenient for initial installations, converting to .pkg format enables granular software maintenance, faster reloads, and reduced memory footprint. This paper outlines the method for converting .bin to .pkg using native Cisco tools.
While less common, you can also "un-convert" a set of packages back into a single .bin file. This is useful for consolidating a system or for archiving a custom configuration.
