## آنچه انجام شد
|
||||
|
||||
### مرحله 1: کشف جداول
|
||||
```bash
|
||||
# تحلیل backup file
|
||||
dbbkup/CMS.sql → 33 جدول شناسایی شد
|
||||
```
|
||||
|
||||
### مرحله 2: Mapping ها
|
||||
**10 جدول با تغییر نام:**
|
||||
- `Categorys` → `Categories`
|
||||
- `FactorDetailss` → `FactorDetails`
|
||||
- `ProductGalleryss` → `ProductGalleries`
|
||||
- `ProductImagess` → `ProductImages`
|
||||
- `Productss` → `Products`
|
||||
- `PruductCategorys` → `ProductCategories`
|
||||
- `PruductTags` → `ProductTags`
|
||||
- `Transactionss` → `Transactions`
|
||||
- `UserAddresss` → `UserAddresses`
|
||||
- `UserCartss` → `UserCarts`
|
||||
|
||||
**23 جدول بدون تغییر نام:**
|
||||
- ClubFeatures, ClubMembershipHistories, ClubMemberships, ...
|
||||
- (لیست کامل در TABLE-MAPPINGS.md)
|
||||
|
||||
### مرحله 3: Configuration
|
||||
```json
|
||||
{
|
||||
"ConnectionStrings": {
|
||||
"SourceDatabase": "185.252.31.42:2019",
|
||||
"TargetDatabase": "194.5.195.53:31433"
|
||||
},
|
||||
"MigrationSettings": {
|
||||
"BatchSize": 1000,
|
||||
"MaxRetryAttempts": 5,
|
||||
"MaxConcurrentTables": 3,
|
||||
"RunPostMigrationTransformation": true
|
||||
},
|
||||
"TableMappings": {
|
||||
/* همه 33 جدول */
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### مرحله 4: Binary Tree Transformation
|
||||
```sql
|
||||
-- ParentId → NetworkParentId + LegPosition
|
||||
-- Validation: Max 2 children per parent
|
||||
-- Auto-fix orphaned nodes
|
||||
-- Full transaction with rollback
|
||||
```

## نحوه استفاده (3 قدم)
|
||||
|
||||
### 1️⃣ تنظیمات
|
||||
```bash
|
||||
cd /home/masoud/Apps/project/FourSat/DataMigration/FourSat.DataMigration
|
||||
nano appsettings.json
|
||||
```
|
||||
|
||||
**تغییرات ضروری:**
|
||||
- `SourceDatabase`: وارد کردن Username/Password
|
||||
- `TargetDatabase`: وارد کردن Username/Password
|
||||
|
||||
### 2️⃣ اجرا
|
||||
```bash
|
||||
dotnet run
|
||||
```
|
||||
|
||||
### 3️⃣ بررسی
|
||||
```bash
|
||||
# Console: مشاهده پیشرفت real-time
|
||||
# Logs: cat Logs/migration-20251206.txt
|
||||
```

## مراحل بعدی پیشنهادی
|
||||
|
||||
1. **Test در Staging**: قبل از production، روی یک دیتابیس تست اجرا کنید
|
||||
2. **Backup**: حتماً Target database را backup بگیرید
|
||||
3. **Performance Tuning**: اگر Network کند است، `BatchSize` را کم کنید
|
||||
4. **Validation**: بعد از migration، integrity check انجام دهید
|
