## Symptoms

- * BGP routemaps stop working correctly after Security Gateway upgrade.

* Comparing the BGP settings in Gaia Database from the original machine and from the upgrade machine shows that BGP "aspath-regex" settings are saved in different ways:

  *Example*:
  * Taken from original R76:

    ```
    
    set routemap Import_Map_1 id 30 match aspath-regex "65002 | 65002 64513 64513 | 65002 64513" origin any
    set routemap Import_Map_2 id 20 match aspath-regex "64513 64513 65002 | 64513 64513 | 64513" origin any
    ```

  * Taken after the upgrade to R77.30:

    ```
    
    set routemap Import_Map_1 id 30 match aspath-regex "65002\\|\\65002\\64513\\64513\\|\\65002\\64513" origin any
    set routemap Import_Map_2 id 20 match aspath-regex "64513\\64513\\65002\\|\\64513\\64513\\|\\64513" origin any
    ```

* "`RTGRTG0019 compile_regex: Regex ... is not a valid GNU regex`" error when trying to remove the involved BGP routemap in Clish.

  *Example* :

  ```
  
  HostName> set routemap Import_Map_2 id 20 off
  RTGRTG0019 compile_regex: Regex "64513\\64513\\65002\\|\\64513\\64513\\|\\64513" is not a valid GNU regex
  ```

## Cause

Format of BGP "aspath-regex" settings in Gaia Database changed in R77.10 and later versions.

During the upgrade from R77 and lower versions, BGP "aspath-regex" settings are not translated correctly to the new format.
