RPA Legacy ERP Data Entry: Keep the Old System Fed While You Plan the Move
For IT heads and operations managers living with an old in-house or vendor ERP: cut the retyping now, without pretending the old system will last forever.
RPA legacy ERP data entry is a practical stopgap. Many Indian businesses run an ERP built years ago, with no usable API and a vendor who has moved on. Data arrives in newer tools and someone retypes it into the old screens every day.
A bot can do that typing if the legacy system opens in a browser. It runs on a Tenant Runner inside your network, so it reaches internal systems over an outbound connection. Desktop-only or terminal screens are outside what these browser bots drive.
This page covers the fit, an illustrative example and the longer-term options.
What retyping into an old ERP costs
Clerks as bridges
Staff hired mainly to move data between systems.
Keying errors
Wrong codes and amounts that surface at month end.
Delays
Records reach the old system a day or two late.
Fragile knowledge
Only a few people know the old screens.
An example: a Vadodara chemicals maker
Take an illustrative maker whose in-house ERP runs on an internal web server. Dispatch data came from a newer system and two clerks keyed about 150 delivery entries a day into the old one.
One delivery entry, keyed by the bot
Work item, delivery entry
A row from the newer system's daily file.
One item per delivery, deduplicated by number.
Reaches the internal ERP from inside the network.
The same steps a clerk followed, recorded.
Proof kept with the run.
Unknown customer codes left for a clerk.
The two clerks moved to checking exceptions and customer queries. Entries reached the old ERP the same day, and the IT head used the breathing room to plan moving that module off the legacy system.
Choosing a legacy ERP integration route
If the old system has a database you can read or an API, an integration is sturdier than screen entry. If the module can move, migration ends the problem. A bot is the right choice when neither is possible yet and the retyping is costing real hours.
Manual retyping against an Apragya bot
| Feature | Manual retyping | Apragya RPA bot |
|---|---|---|
| Speed | As fast as the clerk | Steady, all day |
| Duplicates | Checked by memory | Blocked by a unique key |
| Failures | Noticed later | Retried, then flagged |
| Reach | At a desk in the office | A runner inside your network |
| When screens change | Clerk adapts | Bot updated and republished |

How legacy system data entry automation works
Step 1 of 5
Work queue
Each record is an item with a unique key, so nothing is entered twice.
- Work queue: Each record is an item with a unique key, so nothing is entered twice.
- Tenant Runner: Runs inside your network over an outbound connection.
- Recorded steps: Built in Vibe Studio by recording the clerk's screens.
- Retries: Failed items retried by policy, then set aside for a person.
- Proof: Screenshots and results kept for each run.
What sets Apragya apart
Work queues
Many runners can drain one queue without doubling up.
No inbound firewall rule
The runner connects out to Apragya.
Other routes too
Postgres, SAP and custom connectors where they fit.
AI with review
An agent can check items before they are keyed.
Versioned bots
Roll back if a change breaks a run.
A place to move to
Apragya modules can replace the old ones in stages.

Getting started
- List the screens clerks key into and the volume per day.
- Check whether the system has a readable database or an API.
- Install a Tenant Runner on a machine that can reach it.
- Record one entry flow and test it on a copy if you have one.
- Run a week in parallel with the clerks before switching.
Treat the bot as a bridge. Plan which modules will move and when.
