# Fixing Template Errors After Template Migration
###  Problem
You or a client just used the standard migration method under S-Docs Setup to migrate templates from one org to another. Afterwards, most or all of those templates trigger an error upon use until you go to that template and manually re-save it.
###  Solution
{% stepper %}
{% step %}
### Step: Verify templates have errors
Start by verifying the field `SDOC__Has_Error__c` is set to true for those templates. Spot checking only a couple should be fine. To get a full list, run the following query in Salesforce Inspector:
```sql
SELECT Id FROM SDOC__SDTemplate__c WHERE SDOC__Has_Error__c = true
```
{% endstep %}
{% step %}
### Step: Add Apex class to toggle the field
Add the following Apex class to auto-toggle that field from `TRUE` to `FALSE`:
```java
public class HasErrorToggler {
public static void toggleBooleanField(List records, String fieldName) {
if (records == null || records.isEmpty()) return;
for (SObject rec : records) {
Boolean currentValue = (Boolean) rec.get(fieldName);
rec.put(fieldName, currentValue == null ? true : !currentValue);
}
update records;
}
}
```
{% endstep %}
{% step %}
### Step: Run the Apex class
Then, run a simple command in the Developer Console to run the Apex class:
```java
List temps = [
SELECT Id, SDOC__Has_Error__c
FROM SDOC__SDTemplate__c
WHERE SDOC__Has_Error__c = true
];
HasErrorToggler.toggleBooleanField(temps, 'SDOC__Has_Error__c');
```
{% hint style="info" %}
By adding a `LIMIT 1` to the query, you can verify if this is working. You’ll see the record count in Salesforce Inspector drop by 1.
{% endhint %}
{% endstep %}
{% step %}
### Step: Test generation
Finally, try to generate a document with a couple of the templates that previously errored. They should generate.
{% hint style="info" %}
Keep in mind, some templates may still trigger that same error. This means there is something else keeping it from toggling, such as an invalid ID in the preview ID field, or it references a component that no longer exists, etc.
{% endhint %}
{% endstep %}
{% endstepper %}
